Feature: Add support for using SetHandler together with mod_proxy.
Reason: There was no way to use SetHandler with mod_proxy to configure it to use proxy for the incoming requests. This is useful for using for example php-fpm with event or worker MPM.
Result: SetHandler directive has been improved to allow setting proxy as a handler in, for example, following format: SetHandler "proxy:fcgi://127.0.0.1:9000".

Using php-fpm with actual httpd 2.4.6 package needs use of ProxyPassMatch directive which can lead to malicious code execution. Example: Using the following directive: ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://127.0.0.1:9000/path/to/your/documentroot Malicious code injection: /uploads/malicious.jpg/lalalaalala.php will lead php-fpm to execute malicious.jpg (source https://wiki.apache.org/httpd/PHP-FPM ) Might the SetHanlder enhancement be considered as a security enhancement and therefore backported ?

The simple and common way to enable PHP support in Apache http server is using mod_php and SetHandler application/x-httpd-php Using httpd with worker or event MPM doesn't have support for mod_php With RHSCL various PHP versions are available, but only one mod_php can be enabled. The solution is to use php-fpm and mod_proxy_fcgi. But configuration, to redirect PHP script to FPM, requires to use ProxyPass(Match) which is really not simple. As ProxyPass is evaluated in the very beginning of an http request, it don't honours alias or htaccess rules. SetHandler is evaluated at the very end of an http request. httpd 2.4.10 have SetHandler to proxy support which allow to use SetHandler "proxy:fcgi://127.0.0.1:9000" Please consider backporting this great feature in RHEL For memory, commit in fedora (at 2.4.9 time) http://pkgs.fedoraproject.org/cgit/httpd.git/commit/?id=5b3da1ff0f24d6da3394e65c24656ab77dada3b3
