annotate src/http/modules/ngx_http_ssi_filter_module.c @ 629:65bf042c0b4f release-0.3.36
nginx-0.3.36-RELEASE import
*) Feature: the ngx_http_addition_filter_module.
*) Feature: the "proxy_pass" and "fastcgi_pass" directives may be used
inside the "if" block.
*) Feature: the "proxy_ignore_client_abort" and
"fastcgi_ignore_client_abort" directives.
*) Feature: the "$request_completion" variable.
*) Feature: the ngx_http_perl_module supports the $r->request_method
and $r->remote_addr.
*) Feature: the ngx_http_ssi_module supports the "elif" command.
*) Bugfix: the "\/" string in the expression of the "if" command of the
ngx_http_ssi_module was treated incorrectly.
*) Bugfix: in the regular expressions in the "if" command of the
ngx_http_ssi_module.
*) Bugfix: if the relative path was specified in the
"client_body_temp_path", "proxy_temp_path", "fastcgi_temp_path", and
"perl_modules" directives, then the directory was used relatively to
a current path but not to a server prefix.
