Server cache and blah..
Posted on 1998-09-02
my web site is located on a virtual server running IIS4. on the site, i'm hosting a webcam and a few isapi extensions..
the problem is, the server is set up to cache files.. when, for example, a few people look at the webcam for a few minutes, the picture will hang after a while because the server begins caching it. thus it won't reload the newest picture even though it's reloading..
this caching ALSO causes a problem for my isapi dlls.. apparently, when a dll is loaded on my site, the nt box won't let go of it incase i need to delete/update it..
i know caching can be turned off on the server, but 1) i don't have access to the server (because again, it's a virtual host and i have no physical contact with the machine) and 2)my provider says the only way they know how to disable the cache is to disable it for the whole machine.. obviously this would slow down the machine considerably..
my question: is there a way to write something in my html files that will make sure the file doesn't get cached? or is there another way to get around this?
