Symptoms

When you change files in a non-virtual root (VROOT) directory, Internet Information Services (IIS) does not flush the cache. Therefore, client users who gain access to these pages do not see the changes.

Cause

This problem occurs because IIS directory monitors only VROOT directories (VROOTs that are defined in the IIS metabase). If a filter (URL_MAP filter) changes the physical path of a file to a path that is not defined in IIS as a VROOT path, the IIS code automatically tries to cache the file contents. Because IIS is not monitoring the file's new directory, if the file changes, IIS does not flush the cache to refresh the file.
