comparison src/http/ngx_http_copy_filter_module.c @ 501:d4ea69372b94 release-0.1.25
nginx-0.1.25-RELEASE import
*) Bugfix: nginx did run on Linux parisc.
*) Feature: nginx now does not start under FreeBSD if the sysctl
kern.ipc.somaxconn value is too big.
*) Bugfix: if a request was internally redirected by the
ngx_http_index_module module to the ngx_http_proxy_module or
ngx_http_fastcgi_module modules, then the index file was not closed
after request completion.
*) Feature: the "proxy_pass" can be used in location with regular
expression.
*) Feature: the ngx_http_rewrite_filter_module module supports the
condition like "if ($HTTP_USER_AGENT ~ MSIE)".
*) Bugfix: nginx started too slow if the large number of addresses and
text values were used in the "geo" directive.
*) Change: a variable name must be declared as "$name" in the "geo"
directive. The previous variant without "$" is still supported, but
will be removed soon.
*) Feature: the "%{VARIABLE}v" logging parameter.
*) Feature: the "set $name value" directive.
*) Bugfix: gcc 4.0 compatibility.
*) Feature: the --with-openssl-opt=OPTIONS autoconfiguration directive.
