Changes with nginx 0.2.6 05 Oct 2005

    *) 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.
