Does Internet Explorer cache a value indicating that an image isn't there (404 Error) if you revisit the site some seconds after the first visit?
In short:
- First visit of site A with an image that was deleted before
- First visit of site B
- Second visit of site A, IE doesn shows any "square with red x" ...
I believe it does, yes.
However, if you wish to force IE into attempting to reload that image, initiate a "hard-refresh" by pressing Ctrl + F5
