nginx 1.1.15 *) Feature: the "disable_symlinks" directive. *) Feature: the "proxy_cookie_domain" and "proxy_cookie_path" directives. *) Bugfix: nginx might log incorrect error "upstream prematurely closed connection" instead of correct "upstream sent too big header" one. Thanks to Feibo Li. *) Bugfix: nginx could not be built with the ngx_http_perl_module if the --with-openssl option was used. *) Bugfix: internal redirects to named locations were not limited. *) Bugfix: calling $r->flush() multiple times might cause errors in the ngx_http_gzip_filter_module. *) Bugfix: temporary files might be not removed if the "proxy_store" directive were used with SSI includes. *) Bugfix: in some cases non-cacheable variables (such as the $args variable) returned old empty cached value. *) Bugfix: a segmentation fault might occur in a worker process if too many SSI subrequests were issued simultaneously; the bug had appeared in 0.7.25.
