texte = A site that I'm working on is having serious problems when viewed via AOL's built-in browser. It appears that AOL's proxy system is being too enthusiastic when caching pages and isn't refreshing dynamically-created pages when it should. Fortunately, it looks like I can solve the problem by modifying some headers. To that end, I've added the following tag to a page:[setMIMEHeader name=Cache-control&value=proxy-revalidate]Which should cause the proxy to revalidate at each request. Unfortunately, when I list the MIME headers on the page, I get:12) Cache-control = Max-age=259200Which is the same as if I'd done nothing at all. I've also tried[setMIMEHeader name=Cache-control&value=max-age=0]and would rather use, but it also appears to have no effect (is there a problem by having an = in the value definition?)Is there someplace special the [setMIMEHeader] needs to be placed? Anyone able to get something like this to work?Rob Marquardt Designer/Resident Wirehead Toast Design300 First Avenue North, Suite 150 Minneapolis MN 55401 612.330.9863 v 612.321.9424 f www.toastdesign.com Associated Messages, from the most recent to the oldest:
