FilterEnableCache Metabase Property (IIS 6.0)
The FilterEnableCache property can be set on individual filters to mark them cache friendly to HTTP.sys. Cache friendly means that the filter does not conditionally reroute URLs for /default.htm to either /default-1.htm or /default-2.htm, which would break the HTTP.sys cache. By default, filters are considered unfriendly to the HTTP.sys cache.
You can configure this property at the following locations in the IIS metabase.
For general code examples, see Code Examples to Configure Metabase Properties.
