    # mod_proxy_handler

    This module for apache 2.4 allows you to use e.g. mod_proxy_fcgi in AddHandler or SetHandler directives.

    ## Compile and install the module with apxs:

    apxs -i -a -c mod_proxy_handler.c

    ## Example:

    Send php files to php-fpm running on a TCP socket:

    ```
    # set handler for php
    LoadModule proxy_handler_module modules/mod_proxy_handler.so
    <FilesMatch \.php$>
    SetHandler "proxy:fcgi://127.0.0.1:9000/"
    </FilesMatch>
    # configuration for phpmyadmin package in archlinux
    Alias /phpmyadmin "/usr/share/webapps/phpMyAdmin"
    <Directory "/usr/share/webapps/phpMyAdmin">
    DirectoryIndex index.html index.php
    AllowOverride All
    Options FollowSymlinks
    Require all granted
    </Directory>
    ```
