The first line tells the browser not to cache the page. and the second does basically the same thing

Expiration date of the document. Essentially this will cause a document to be reloaded from the website after the date (even if it is stored in the user's cache). Put a date in the past to disable caching of the document.

-1 is just an invalid date, so that it never caches. If some computer has a slow clock and says the date is yesterday, then it will still cache. -1 never caches, because the date is never -1. The two tags are supported by different browsers. I generally skip the pragma one, but I think that one works for Netscrape or something.http://www.htmlgoodies.com/beyond/referenc...cle.php/3472881
