[PHP] Help me to win the battle with browser's cache
Hello php-general, I have index.php, which has a href=index.php?logoutLog out/a. When I click it, I am logged out the site. But I type index.php in browser's address bar, press Enter and ... it shows non-logouted page. What should I write in php code to tell browser something like forget about old page, don't display it, get the newest version? Some time ago I tried to do that in several ways and nothing gived 100% result. And other thing I saw was that Netscape and Explorer behave in different ways in such cases. Could someone help me? Maybe this topic was discussed before, but still... I appreciate greatly any suggestion. -- Olexandr Vynnychenko mailto:[EMAIL PROTECTED] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Re: [PHP] Help me to win the battle with browser's cache
Hi
I've found some code which i put it into this function. I've never got the
meta tag technique to work but this seems to do the trick.
Call noCache() before outputting anything to the page.
function noCache() {
header (Expires: Mon, 26 Jul 1997 05:00:00 GMT);// Date in the past
header (Last-Modified: . gmdate(D, d M Y H:i:s) . GMT); // always
modified
header (Cache-Control: no-cache, must-revalidate); file://HTTP/1.1
header (Pragma: no-cache); // HTTP/1.0
}
Regards
Girish

Thanks! That's what I've been looking for. But there is something
wrong with this headers. I pasted the code above, and peges really
stopped loading from cache. But... I tested it with IE 5.5 SP2 and
Netscape 4.77 (I don't use Netscape 6.x because it's just useless
cputime eater). The page works fine with Navigator, but IE shows blank
page each time I click a link. It shows the page properly only after
clicking Refresh. I remember I have the same problem 1/2 year ago when
I was unsuccesfully tried to win the battle with the browser cache :).
Now I commented the 3rd header (with cache-control), and now IE
works perfect too. I don't know why it works on your pages :). The
problem is not in my personal IE because the same problem was (as I
said) whan I used IE 5.0.
So, if there are some people who have the same problem, I would
suggest to put these 3 lines on the top of the page:
header(Expires: Mon, 26 Jul 1997 05:00:00 GMT);
header(Last-Modified: .gmdate(D, d M Y H:i:s). GMT);
header(Pragma: no-cache);
Thanks to Girish and others who tried to help me!
P.S. There can be another problem: client's clock. If it's 20 Jan 1985
on client's machine, than ... Do you think I can put in the first
header some very old date like 1 Jan 1970? I just want it to work in
any case.
