There is a mechanisme in the H1 and H2 multiplexer to skip the payload when a response is returned to the client when it must not contain any payload (response to a HEAD request or a 204/304 response). However, this does not work when the splicing is used. The H2 multiplexer does not support the splicing, so there is no issue. But with the mux-h1, when data are sent using the kernel splicing, the mux on the server side is not aware the client side should skip the payload. And once the data are put in a pipe, there is no way to stop the sending. It is a defect of the current design. This will be easier to deal with this case when the mux-to-mux forwarding will be implemented. But for now, to fix the issue, we should add an HTX flag on the start-line to pass the info from the client side to the server side and be able to disable the splicing in necessary. The associated reg-test was improved to be sure it does not fail when the splicing is configured. This patch should be backported as far as 2.4.. |

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)
