ATL Server Library Reference 
ATL_STENCIL_CHECK_TIMEOUT 

This macro defines the frequency with which ATL Server checks cached stencils against the raw stencil file to determine if the cached version is out of date.


#define ATL_STENCIL_CHECK_TIMEOUT 1000

The CIsapiExtension class uses the CStencilCache class to cache preprocessed stencils. This macro determines how often stencils retrieved from the cache are checked for obsolescence. If the raw stencil file from which the cached stencil was derived has changed, or cannot be opened, the CIsapiExtension class removes the cached stencil. Unless redefined, this macro resolves to 1,000 milliseconds (10 seconds).
