Wininet Cache Issues

Jeffdav’s weblog has an entry on why view->source sometimes stops working and why you get forced to save some images as bmp when they really aren’t. While you are waiting for the fix, the workaround we use on the Longhorn Wininet team is to lower our cache size down to something more reasonable. Mine is set to 60 Mb. Not to worry, this won’t affect downloading large files.

The setting is available on Tools->Internet Options->Temporary Internet Files->Settings.

I believe that the default for the setting is based on the hard drive size, so you are more likely to run into the issues on a newer machine with a bigger hard drive partition.

    View source and saving images in their original format also don’t work when they’re served as not cachable or when you disable the cache (as you can for SSL connections). So even when the IE team fixes their issues you should still use a real browser that will give you the page source as it loaded it instead of a cache file.
