This metabase property indicates which file name extensions are supported by the compression scheme. The output from dynamic files with the specified file extensions will be compressed by IIS.
Important Setting this parameter to an empty string can have an adverse effect on your server’s performance.
If this parameter is empty then all dynamic responses are sent compressed. In addition, any static file type not specified in HcFileExtensions will also be dynamically compressed and therefore not cached.
Also, HcDoDynamicCompression must be set to TRUE for dynamic compression to be performed.
The Web service must be restarted before any changes to this property take effect.
