Q226 How can I avoid 'persistent frame caching' when I use dynamic pages in my frames?

You are here: irt.org | FAQ | JavaScript | Frame | Q226 [ previous next ]

Add these META tags in your html page:

<META HTTP-EQUIV="refresh" CONTENT="999999999;">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="expired" CONTENT="01-Mar-94 00:00:01 GMT">

The refresh is for a bug in Communicator, when you set a refresh tag in a frame, and use the location.replace() method to put in a new page, the refresh timer stays active putting back the old page.

Thanks to Ren Hoek for this tip.

The "999999999" in the refresh META tag will cause a page to refresh indefinitely in Win Internet Explorer 5.x under Win 2K or NT.

For some reason, 500363690 is the magic number... any setting of 500363690 or higher causes Internet Explorer to refresh indefinitely. 500363689 will not. Weird but true.
