Working on a project where we are storing pictures(.png) on IIS 6. These pictures get overwritten every second, with the same filename.
I can go to the directory, open the picture, and view the most recent update. However, if I type in the address in Internet Explorer, an older version of the picture displays in the browser.
What makes this interesting is if I type that same address in another browser, specifically FireFox and Chrome, I always see the most recent updated picture.
How or why does this happen? Caching issue? Same behavior from multiple PC's, get an old version from a PC that never access the address, so not likely to be related to the PC accessing the picture.
The only way we have found to resolve this issue is to set a task to reset the IIS every hour.
Thoughts?
