This support function is an improved version of the HSE_REQ_MAP_URL_TO_PATH support function. It allows your ISAPI extension to map a logical URL path to a physical path, as well as gather several types of attributes that are associated with that physical path, such as access-control or cache-control flags.
Here are some examples of virtual-to-physical path mappings:
/scripts becomes C:\InetPub\scripts
/scripts/oop becomes C:\InetPub\scripts\oop
