High-Speed Push-Technology Program May Overwrite Internet Cache

ID: Q234266

The information in this article applies to:

Microsoft Internet Explorer version 5 for Windows 95
Microsoft Internet Explorer version 5 for Windows 98
Microsoft Internet Explorer version 5 for Windows NT 4.0

SYMPTOMS

A high-speed push-technology program that uses Internet Software Design Kit (InetSDK) function calls may overwrite the Internet Explorer cache limit and possibly fill up the hard disk.

CAUSE

The scavenger thread that cleans up the Internet Explorer cache has a minimum cache life limit of 10 minutes. If an item in the cache is less than 10 minutes old, the scavenger thread does not remove that item from the cache. For some very high-speed, large-file, push-technology programs, this cache time limit causes the program to overwrite the Internet Explorer cache and possibly fill the hard disk.

RESOLUTION
