# Enable gzip - by Jerryhuang

    SetOutputFilter DEFLATE
    SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary
    SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
    SetEnvIfNoCase Request_URI .(?:pdf|mov|avi|mp3|mp4|rm)$ no-gzip dont-vary  

    AddOutputFilterByType DEFLATE text/*
