I'm confirmed that when one person hangs downloading images from the site,
other people hang also. This means something is happening on the server
side, but I have no idea what it would be. When it's broken, I can
download CF pages from the site (along with css or .js files), but not
images. I looked at my HTTP headers going to the server, and after
retrieving the .cfm file successfully, it sends two GET requests for images
(the max number of connections?), but they never return, and they do not
time out on the client. It seems to stay in the broken state for 15-20
minutes, and then it resets on the server side (allowing new successful
downloads), but my client shows a page with broken images. The problem is
sporadic, occurring on the order of once every 2 hours when we pound the
site with dummy requests.
One more observation: as a client, I must clear my local cache to observe
the problem. If I already have the images cached, the page downloads fine
even when it's broken, presumably because the "Not modified" responses can
be downloaded in the broken state, but not new images.
Thanks in advance for any ideas or pointers (to IIS problems, image
download problems, or magical incantations) -- this is way out of my
league, but I need to figure it out nonetheless.
