diff src/http/ngx_http_upstream.h @ 464:c8cfb6c462ef NGINX_0_7_44
nginx 0.7.44
*) Feature: the ngx_http_proxy_module preliminary cache support.
*) Feature: the --with-pcre option in the configure.
*) Feature: the "try_files" directive is now allowed on the server
block level.
*) Bugfix: the "try_files" directive handled incorrectly a query string
in a fallback parameter.
*) Bugfix: the "try_files" directive might test incorrectly directories.
*) Bugfix: if there is the single server for given address:port pair,
then captures in regular expressions in a "server_name" directive
did not work.
