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">

You can use both together. http://stackoverflow.com/questions/1341089/using-meta-tags-to-turn-off-caching-in-all-browsers — madhead, Sep 29 '12 at 20:30
Does this effect anything at all? Page load, recursive cache'ing? What are the pros and cons of using both? — Andrew Allen West, Sep 29 '12 at 20:33

User agents are not required to support meta data mechanisms:

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