A TCP/HTTP action can stop the rules evaluation. However, it should be applied on the current section only. For instance, for http-requests rules, an "allow" on a frontend must stop evaluation of rules defined in this frontend. But the backend rules, if any, must still be evaluated. For http-response rulesets, according the configuration manual, the same must be true. Only "allow" action is concerned. However, since the beginning, this action stops evaluation of all remaining rules, not only those of the current section. This patch may be backported to all supported versions. But it is not so critical because the bug exists since a while. I doubt it will break any existing configuration because the current behavior is counterintuitive.
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)
