Refreshing

[The Praetorian]

I've noticed that when I change things on my website, sometimes I actually have to go to one of the pages and hit refresh before the changes will take effect. I use FF as my default brower. Is this a browser issue? Or is there a tag I can add to my code to make it refresh automatically on viewing?

That is the page being cached. Add this to your head to disable caching for the page:<meta http-equiv="Pragma" content="no-cache" /><meta http-equiv="Expires" content="-1" />

Thanks Justsomeguy!Now, just for learning purposes, what exactly does that code tell the browser?

[aspnetguy]

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.

Does that mean I should change the "-1" to say, yesterday's date?

[aspnetguy]

I beleive that is what -1 means, yesterday (1 day ago)

[justsomeguy]

-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
