This metabase 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 will use the matching scheme that has the highest priority number.
Valid priority numbers can be 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 Web service must be restarted before any changes to this property take effect.
