- Implementation Details

Regardless of the Session File Caching setting, an attempt to download a specific file is performed only once per session. If the download was successful, the file is stored in the local Internet cache directory (set on the Internet property sheet). Subsequent requests to display the file will result in the cached copy being used. If the download was unsuccessful, the file will be flagged as unavailable and no further attempts will be made to download it.

The Windows Client maintains an internal structure called the MEMORYCACHE, which is a hash table of graphics by filename (not by full path). If a graphic is found in the MEMORYCACHE, it takes the shortest time to load.
