nginx 0.2.6
*) Change: while using load-balancing the time before the failed
backend retry was decreased from 60 to 10 seconds.
*) Change: the "proxy_pass_unparsed_uri" was canceled, the original URI
now passed, if the URI part is omitted in "proxy_pass" directive.
*) Feature: the "error_page" directive supports redirects and allows
more flexible to change an error code.
*) Change: the charset in the "Content-Type" header line now is ignored
in proxied subrequests.
*) Bugfix: if the URI was changed in the "if" block and request did not
found new configuration, then the ngx_http_rewrite_module rules ran
again.
*) Bugfix: if the "set" directive set the ngx_http_geo_module variable
in some configuration part, the this variable was not available in
other configuration parts and the "using uninitialized variable"
error was occurred; bug appeared in 0.2.2.
