I ran into this problem on a script I was working on this week too... The no cache meta tag isn't supported by IE 4 or 5, I'm not sure about 6... something about the way the file is buffered, IE automatically caches it.
There are work arounds to use the no cache method with explorer, but I haven't experimented with them. Check: http://htmlgoodies.earthweb.com/beyond/nocache.html for more info. For my script, we ended up using the HTTP header cache-control to specify that the page expires immediately... It works like a charm. It's just a simple line, as follows: print "Cache-Control: max-age=0\n"; Hope this helps, Jon -----Original Message----- From: yue lu [mailto:[EMAIL PROTECTED]] Sent: Friday, February 01, 2002 5:49 PM To: [EMAIL PROTECTED] Subject: cache I had a cgi program, and it will dynamically draw a image and load into the cgi program, but because the web browser cache always remember the image file, so it will not update the image unless I quit the browser, restart the browser, then tue image will update. please help me with this problem?
