nginx 0.7.48 *) Feature: the "proxy_cache_key" directive. *) Bugfix: now nginx takes into account the "X-Accel-Expires", "Expires", and "Cache-Control" header lines in a backend response. *) Bugfix: now nginx caches responses for the GET requests only. *) Bugfix: the "fastcgi_cache_key" directive was not inherited. *) Bugfix: the $arg_... variables did not work with SSI subrequests. Thanks to Maxim Dounin. *) Bugfix: nginx could not be built with uclibc library. Thanks to Timothy Redaelli. *) Bugfix: nginx could not be built on OpenBSD; the bug had appeared in 0.7.46.
