Description

Determines whether the redirector caches files that are opened with FILE_SHARE_READ sharing access. Typically, files opened with this access cannot be cached because other processes might be reading the file. This optimization prevents other processes from writing to the file. Set this value to 0 to preserve the strict semantics of the specified sharing modes.
