Hi all!
I'm already using haproxy to proxy some TCP-connections and also have a need to rewrite data in TCP stream. Namely convert graphite protocol to influx line protocol, but that does not mattes. There is alike functionality for HTTP, which allows to replace or rewrite its headers, but I have not see something like it for TCP. And I wondering if it is possible to do without adding additional substances and do it in context of haproxy. I need to read incoming newline-delimited strings and forward modified version of them. I can write Lua-code, but not sure how it should be embedded into haproxy's architecture. The closest I have found is this examples: http://article.gmane.org/gmane.comp.web.haproxy/25243/ But that did not helped me much. Is it possible to solve my task with Lua in haproxy? Can someone help me with code which wraps main functionality (rewriting)?
