### HcFileExtensions

This metabase property indicates which file name extensions are supported by the compression scheme. Only static files with the specified file extensions will be compressed by IIS. If this setting is empty, then no static files are compressed.

In addition to file name extension matches, HcDoOnDemandCompression and HcDoStaticCompression must be set to TRUE for compression to be performed.

The Web service must be restarted for any changes to this property take effect.
