HAProxy and URL Rewriting Configuration

regex wordpress url-rewriting nginx haproxy

Your regex is wrong, you're assuming the server is in the request path. To match the request paths in the headers use a regex like this one:

reqrep ^([^\ ]*)\ /lang/blog/(.*) \1\ /blog/lang/\2

you can use reqirep as well but that is only useful if your servers actually serve /BLog/lAnG/ as well.

If this still doesn't work switch to a stable version, e.g. as of now reqrep is broken in 1.5 dev. Switched to 1.4 to fix.
