agentzh / ngx-lua-req-header-user-agent.patch
Created April 24, 2013 00:23
bugfix: Modifying the User-Agent request header via ngx.req.set_header or ngx.req.clear_header did not update those special internal flags used in the Nginx internals, like "r->headers_in.msie6" and "r->headers_in.opera". Thanks Matthieu Tourne for the patch.

bugfix: modifying the Connection request header via ngx.req.set_header or ngx.req.clear_header did not update the special internal flags in the Nginx core, "r->headers_in.connection_type" and "r->headers_in.keep_alive_n". Thanks Matthieu Tourne for the patch.

agentzh / ngx-lua-set-cookie-header.patch
Created April 24, 2013 19:48
bugfix: modifying the Cookie request headers via ngx.req.set_header or ngx.req.clear_header did not update the Nginx internal data structure, r->headers_in.cookies, at the same time, which might cause issues when reading variables $cookie_COOKIE, for example. thanks Matthieu Tourne for the patch.
