Re: Asp.net 2.0 caching and images

Tech-Archive recommends: Fix windows errors by optimizing your registry

Alex,

Try adding the t=<random>

To the image url instead of the page. IE caches images based on the image
path not the page path. Making it look like the image path has changed will
stop the caching. For example:

http://msdn.microsoft.com/asp.net/art/asprk.jpg?t=1234
