## Dependency Management
### Can WebSocket++ be used without Boost?
Yes. WebSocket++ only uses Boost features as polyfills for C++11 language features and libraries. If you have a C++11 compiler and standard library you can use WebSocket++ without Boost. In most cases setting your build environment to use the C++11 (or later) language dialect is sufficient to enable this mode of use.
With less common compilers (and sometimes very recently release compilers) there may be specific issues with certain libraries that aren't automatically detected by the library. For these situations there are additional defines available to fine tune which C++11 libraries and features are used. TODO: more details about them.
For the iostream/raw transport the C++11 standard library is sufficient. For the Asio based transports, there is no C++11 library that provides the networking capabilaties that Asio does. As such even with a C++11 build system, you will need a standalone copy of Asio to use if Boost Asio is not available.
### Can WebSocket++ be used with standalone Asio
Yes. The process is the same as used with standalone Asio itself. Define `ASIO_STANDALONE` before including Asio or WebSocket++ headers. You will need to download a copy of the Asio headers separately (http://www.think-async.com) and make sure they are in your build system's include path.
### Can WebSocket++ be used without TLS or OpenSSL?
Yes. When using the iostream/raw transport, there are no TLS features and OpenSSL is not required. When using the Asio transport TLS features are optional. You only need OpenSSL if you want to use TLS. You can only make or recieve encrypted connections (https/wss) if you have enabled TLS features.
Whether an Asio endpoint uses TLS or not is determined by its config template parameter. The default bundled `websocketpp::config::asio` and `websocketpp::config::asio_client` configs do not support TLS, the `websocketpp::config::asio_tls` and `websocketpp::config::asio_tls_client` do.
The `<websocketpp/config/asio.hpp>` and `<websocketpp/config/asio_client.hpp>` headers will include both the TLS and non-TLS varients of their respective configs and require the presence of OpenSSL. The `<websocketpp/config/asio_no_tls.hpp>` and `<websocketpp/config/asio_no_tls_client.hpp>` headers will include only the non-TLS configs and do not require OpenSSL.
## Compression
### How do I use permessage-deflate in version 0.6.0-permessagedeflate and 0.7.0?
These versions of the library require a custom config to use the permessage-deflate extension. Here is a minimal example of such a custom config. You can also integrate these lines into an existing custom config.
Note that in these versions there is no fine grained control over which connections are compressed or not. Clients will request compression with the default settings and use it if the server supports it. Servers will accept whatever parameters clients request.
Outgoing messages by default will be compressed if compression was auto-negotiated during the handshake. There is an option to force a specific message to be sent uncompressed even if compression was negotiated. This may be useful for sending data that you know to be compressed already (images, zip files, etc).
__Server Example__
```
#include <websocketpp/extensions/permessage_deflate/enabled.hpp>
struct deflate_server_config : public websocketpp::config::asio {
// ... additional custom config if you need it for other things
/// permessage_compress extension
struct permessage_deflate_config {};
typedef websocketpp::extensions::permessage_deflate::enabled
<permessage_deflate_config> permessage_deflate_type;
};
typedef websocketpp::server<deflate_server_config> server_endpoint_type;
```
__Client Example__
```
#include <websocketpp/extensions/permessage_deflate/enabled.hpp>
struct deflate_client_config : public websocketpp::config::asio_client {
// ... additional custom config if you need it for other things
/// permessage_compress extension
struct permessage_deflate_config {};
typedef websocketpp::extensions::permessage_deflate::enabled
<permessage_deflate_config> permessage_deflate_type;
};
typedef websocketpp::client<deflate_client_config> client_endpoint_type;
```
## Security
### Is it possible to terminate a malicious connection quickly, without tying up resources performing clean close steps,
Yes. The library will automatically detect and terminate connections that violate the WebSocket protocol. In cases where the library believes the remote endpoint to be malicious or sufficiently broken to be unlikely to understand or process the closing handshake, it will be omited.
If your application detects conditions above the protocol level that you believe to be malicious, for example, if you recognize an IP from a known denial of service attack, you can close the connection with two different levels of urgency. Use the standard `websocketpp::endpoint::close` or `websocketpp::connection::close` methods with one of the following special close codes:
- `websocketpp::close::status::omit_handshake`: Omits the closing handshake, but cleanly closes the TCP connection.
- `websocketpp::close::status::force_tcp_drop`: Forcibly drop the TCP connection.
Please note that usage of these disconnect methods results in a violation of the WebSocket protocol and may have negative reprocusions for the remote endpoint with respect to network timeouts. Please use caution when using them.
## Build Issues
### Getting compile errors related to `std::chrono`, `boost::chrono`, `waitable_timer`, or `steady_clock`
Your build system may be confused about whether it is supposed to be using `boost::chrono` or `std::chrono`. Boost automatically detects this setup on some compilers but not others. Defining `BOOST_ASIO_HAS_STD_CHRONO` can help. See http://www.boost.org/doc/libs/1_60_0/doc/html/boost_asio/overview/cpp2011/chrono.html for more details.

/** \page getting_started Getting Started
WebSocket++ code is available on github at https://github.com/zaphoyd/websocketpp
The official project homepage lives at http://www.zaphoyd.com/websocketpp
The git repository is organized into several directories:
- **docs**: This documentation
- **examples**: Example programs that demonstrate how to build basic versions of some commonly used patterns for WebSocket clients and servers.
- **test**: Unit tests that confirm that the code you have works properly and help detect platform specific issues.
- **tutorials**: Detailed walkthroughs of a select set of the example programs.
- **websocketpp**: All of the library code and default configuration files.
WebSocket++ is a header only library. You can start using it by including the websocketpp source directory in your project's include path and including the appropriate WebSocket++ headers in your program. You may also need to include and/or link to appropriate Boost/system libraries. TODO: More information: Building a program with WebSocket++, Walkthroughs of the example programs
WebSocket++ includes cmake and scons scripts for building the examples and unit tests. Neither system is needed unless you want to build tests or examples in an automated fashion.
__Usage questions__ should be posted to the project mailing list at http://groups.google.com/group/websocketpp/ or the IRC channel (\#websocketpp on freenode).
__Bugs and issues__ should be posted to the project GitHub issues queue: https://github.com/zaphoyd/websocketpp/issues.
__Pull requests__ on GitHub are welcome. Please make them against the `develop` branch.
WebSocket++ is written and maintained by Peter Thorson. You can contact me via GitHub messaging, IRC, or via email at websocket@zaphoyd.com.

/** \page reference.handlers Handler Reference
Handlers allow WebSocket++ programs to receive notifications about events
that happen in relation to their connections. Some handlers also behave as
hooks that give the program a chance to modify state or adjust settings before
the connection continues.
Handlers are registered by calling the appropriate `set_*_handler` method on either an
endpoint or connection. The * refers to the name of the handler (as
specified in the signature field below). For example, to set the open handler,
call `set_open_handler(...)`.
Setting handlers on an endpoint will result in them being copied as the default
handler to all new connections created by that endpoint. Changing an endpoint's
handlers will not affect connections that are already in progress. This includes
connections that are in the listening state. As such, it is important to set any
endpoint handlers before you call `endpoint::start_accept` or else the handlers
will not be attached to your first connection.
Setting handlers on a connection will result in the handler being changed for
that connection only, starting at the next time that handler is called. This can
be used to change the handler during a connection.
Connection Handlers
-------------------
These handlers will be called at most once per connection in the order specified below.
### Socket Init Handler
| Event | Signature | Availability |
| --------------------- | ----------------------------------------------------- | -------------------- |
| Socket initialization | `socket_init(connection_hdl, asio::ip::tcp::socket&)` | 0.3.0 Asio Transport |
This hook is triggered after the socket has been initialized but before a connection is established.
It allows setting arbitrary socket options before connections are sent/recieved.
### TCP Pre-init Handler
| Event | Signature | Availability |
| ----------------------------- | ------------------------------ | -------------------- |
| TCP established, no data sent | `tcp_pre_init(connection_hdl)` | 0.3.0 Asio Transport |
This hook is triggered after the TCP connection is established, but before any pre-WebSocket-handshake
operations have been run. Common pre-handshake operations include TLS handshakes and proxy connections.
### TCP Post-init Handler
| Event | Signature | Availability |
| ----------------------- | ------------------------------------------ | ----------------------------- |
| Request for TLS context | `tls_context_ptr tls_init(connection_hdl)` | 0.3.0 Asio Transport with TLS |
This hook is triggered before the TLS handshake to request the TLS context to use. You must
return a pointer to a configured TLS conext to continue. This provides the opportuinity to
set up the TLS settings, certificates, etc.
### Validate Handler
| Event | Signature | Availability |
| ------------------------------------- | ------------------------------- | ---------------------------- |
| Hook to accept or reject a connection | `bool validate(connection_hdl)` | 0.3.0 Core, Server role only |
This hook is triggered for servers during the opening handshake after the request has been
processed but before the response has been sent. It gives a program the opportunity to inspect
headers and other connection details and either accept or reject the connection. Validate happens
before the open or fail handler.
Return true to accept the connection, false to reject. If no validate handler is registered,
all connections will be accepted.
### Open Connection Handler
| Event | Signature | Availability |
| ------------------------- | ---------------------- | ------------ |
| Successful new connection | `open(connection_hdl)` | 0.3.0 Core |
Either open or fail will be called for each connection. Never both. All
connections that begin with an open handler call will also have a matching
close handler call when the connection ends.
### Fail Connection Handler
| Event | Signature | Availability |
| ----------------------------------- | ---------------------- | ------------ |
| Connection failed (before opening) | `fail(connection_hdl)` | 0.3.0 Core |
Either open or fail will be called for each connection. Never both. Connections
that fail will never have a close handler called.
### Close Connection Handler
| Event | Signature | Availability |
| --------------------------------- | ----------------------- | ------------ |
| Connection closed (after opening) | `close(connection_hdl)` | 0.3.0 Core |
Close will be called exactly once for every connection that open was called for.
Close is not called for failed connections.
Message Handlers
----------------
These handers are called in response to incoming messages or message like events. They only will be called while the connection is in the open state.
### Message Handler
| Event | Signature | Availability |
| --------------------- | -------------------------------------- | ------------ |
| Data message recieved | `message(connection_hdl, message_ptr)` | 0.3.0 Core |
Applies to all non-control messages, including both text and binary opcodes. The
`message_ptr` type and its API depends on your endpoint type and its config.
### Ping Handler
| Event | Signature | Availability |
| ------------- | ---------------------------------------- | ------------ |
| Ping recieved | `bool ping(connection_hdl, std::string)` | 0.3.0 Core |
Second (string) argument is the binary ping payload. Handler return value
indicates whether or not to respond to the ping with a pong. If no ping handler
is set, WebSocket++ will respond with a pong containing the same binary data as
the ping (Per requirements in RFC6455).
### Pong Handler
| Event | Signature | Availability |
| ------------- | ----------------------------------- | ------------ |
| Pong recieved | `pong(connection_hdl, std::string)` | 0.3.0 Core |
Second (string) argument is the binary pong payload.
### Pong Timeout Handler
| Event | Signature | Availability |
| ---------------------------------- | ------------------------------------------- | ---------------------------------------- |
| Timed out while waiting for a pong | `pong_timeout(connection_hdl, std::string)` | 0.3.0 Core, transport with timer support |
Triggered if there is no response to a ping after the configured duration. The second
(string) argument is the binary payload of the unanswered ping.
### HTTP Handler
| Event | Signature | Availability |
| --------------------- | --------------------- | ---------------------------- |
| HTTP request recieved | `http(connection_hdl` | 0.3.0 Core, Server role only |
Called when HTTP requests that are not WebSocket handshake upgrade requests are
recieved. Allows responding to regular HTTP requests. If no handler is registered
a 426/Upgrade Required error is returned.
### Interrupt Handler
| Event | Signature | Availability |
| ----------------------------------- | --------------------------- | ------------ |
| Connection was manually interrupted | `interrupt(connection_hdl)` | 0.3.0 Core |
Interrupt events can be triggered by calling `endpoint::interrupt` or `connection::interrupt`.
Interrupt is similar to a timer event with duration zero but with lower overhead. It is useful
for single threaded programs to allow breaking up a very long handler into multiple parts and
for multi threaded programs as a way for worker threads to signale to the main/network thread
that an event is ready.

/** \mainpage
WebSocket++ is a C++ library that can be used to implement WebSocket functionality. The goals of the project are to provide a WebSocket implementation that is portable, flexible, lightweight, low level, and high performance.
WebSocket++ does not intend to be used alone as a web application framework or full featured web services platform. As such the components, examples, and performance tuning are geared towards operation as a WebSocket client or server. There are some minimal convenience features that stray from this (for example the ability to respond to HTTP requests other than WebSocket Upgrades) but these are not the focus of the project. In particular WebSocket++ does not intend to implement any non-WebSocket related fallback options (ajax / long polling / comet / etc).
In order to remain compact and improve portability, the WebSocket++ project strives to reduce or eliminate external dependencies where possible and appropriate. WebSocket++ core has no dependencies other than the C++11 standard library. For non-C++11 compilers the Boost libraries provide drop in polyfills for the C++11 functionality used.
WebSocket++ implements a pluggable data transport component. The default component allows reduced functionality by using STL iostream or raw byte shuffling via reading and writing char buffers. This component has no non-STL dependencies and can be used in a C++11 environment without Boost. Also included is an Asio based transport component that provides full featured network client/server functionality. This component requires either Boost Asio or a C++11 compiler and standalone Asio. As an advanced option, WebSocket++ supports custom transport layers if you want to provide your own using another library.
In order to accommodate the wide variety of use cases WebSocket++ has collected, the library is built in a way that most of the major components are loosely coupled and can be swapped out and replaced. WebSocket++ will attempt to track the future development of the WebSocket protocol and any extensions as they are developed.
