For filters written in lua, the tcp payloads will be filtered using methods exposed by the Channel class. So the corrsponding C binding functions must be prepared to process payload in a filter context and not only in an action context. The main change is the offset where to start to process data in the channel buffer, and the length of these data. For an action, all input data are considered. But for a filter, it depends on what the filter is allow to forward when the tcp_payload callback function is called. It depends on previous calls but also on other filters. In addition, when the payload is modified by a lua filter, its context must be updated. Note also that channel functions cannot yield when called from a filter context. For now, it is not possible to define callbacks to filter data and the documentation has not been updated. |

The HAProxy documentation has been split into a number of different files for ease of use. Please refer to the following files depending on what you're looking for : - INSTALL for instructions on how to build and install HAProxy - BRANCHES to understand the project's life cycle and what version to use - LICENSE for the project's license - CONTRIBUTING for the process to follow to submit contributions The more detailed documentation is located into the doc/ directory : - doc/intro.txt for a quick introduction on HAProxy - doc/configuration.txt for the configuration's reference manual - doc/lua.txt for the Lua's reference manual - doc/SPOE.txt for how to use the SPOE engine - doc/network-namespaces.txt for how to use network namespaces under Linux - doc/management.txt for the management guide - doc/regression-testing.txt for how to use the regression testing suite - doc/peers.txt for the peers protocol reference - doc/coding-style.txt for how to adopt HAProxy's coding style - doc/internals for developer-specific documentation (not all up to date)
