annotate src/core/ngx_inet.c @ 517:dadfa78d2270 release-0.1.33
nginx-0.1.33-RELEASE import
*) Bugfix: nginx could not be built with the --without-pcre parameter;
the bug had appeared in 0.1.29.
*) Bugfix: 3, 4, 7, and 8 the "proxy_set_header" directives in one
level cause the bus fault on start up.
*) Bugfix: the HTTP protocol was specified in the HTTPS redirects.
*) Bugfix: if the "rewrite" directive used the captures inside the "if"
directive, then the 500 error code was returned.
