HcPriority

The HcPriority property specifies the priority rating assigned to a particular compression scheme. If your installation of IIS has multiple compression schemes installed and a client browser indicates, in the Accept-Encoding header, that it can handle multiple compression schemes, IIS uses the priority numbers specified in HcPriority to determine which scheme to use for the request. In that case, IIS uses the matching scheme that has the highest priority number.

Valid priority numbers range from 1 to 10. In general, if you have multiple compression schemes installed with IIS, you should assign each compression scheme a different priority number.

The World Wide Web Publishing Service (WWW service) must be restarted before any changes to this property take effect.
