Can I use the Meta tag to stop the web pages from caching? thanks

It's not very reliable, infact I don't even think it works, but you can use this:

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">

I heard somewhere that the Pragma one only works on Netscape... I have seen this one in tutorials before:

<meta http-equiv="Cache-Control" content="no-cache">

I think that IE doesn't really listen to any of it though. hmm...

Hi,
http-equiv meta tags are generally supposed to emulate HTTP headers usually sent by the server. That's right - they are unreliable and often wont work at all. Anyway, try these:

<META HTTP-EQUIV="Pragma" CONTENT="no-cache"> - for HTTP 1.0 legacy protocol

<meta http-equiv="Cache-Control" content="no-store, no-cache, must-revalidate"> - not sure if they can be used in the same meta tag, or You'll have to write separate ones... As true HTTP header, they can be sent together...

<meta http-equiv="Expires" content="Mon, 26 Jul 1997 05:00:00 GMT"> - a date in the past...
