I'm guessing the answer is no as i'm unable to find anything in the documentation that suggests otherwise, but..
If I wanted to change the error return code submitted by haproxy (not the backend server) is this possible? i.e. change haproxy to return a 502 when it's going to return a 504? I know the current return codes are correct as of http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html - I could just do with this short hack. Thanks, Matt
