Using <meta> tags to turn off caching in all browsers?

I am just curious as one html tag it's efficient for no-cache.

<META HTTP-EQUIV="CACHE-CONTROL" CONTENT="NO-CACHE">

or

<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
Was it helpful?

Solution

User agents are not required to support meta data mechanisms:

http://www.w3.org/TR/html401/struct/global.html#h-7.4.4.1

Using one or both shouldn't cause problems, but it would probably be more effective to send a NO-CACHE directive over HTTP.
