Session or browser problem??

Hi all,

I have a news website tat is developed on joomla 1.5.Login facility is
done thru a login component.On each page,ther s a 'Log In' link that
redirects them to a login page.On successful login,user details are
set in session as well as cookies and then redirected back to d
referring page.The 'Log In' section changes to 'Welcome user',along
wid a 'Log Out' link.All this works d same in IE 6 as well as in FF
2.The difference comes durin log out action.

In FF,on clickin 'Log Out',the required session vars are set '' as
well as cookies in d component and then redirected back to referring
page.The login bar changes back to 'Log in'.But in IE,once redirected
from the component,the page still shows the login bar as 'Welcome
user'.Only if i manually click the refresh button (of IE), the page
gets refreshed and the login bar shows logged out status.

Any help wud be highly appreciated...

Hi,

Try using session_cache_limiter('nocache') before session_start. This
will tell the browser not to cache the page.

Which the browser can ignore, unfortunately. And even if the browser
doesn't ignore the cache, any of the systems between the client and the
server could cache it.

How I wish it did work properly.

P.S. Please don't top post.

Try using 'nocache' instead of 'none'. This will set the Cache-
Control, Expires, and Pragma headers as below. The 'none' value won't
define any additional cache headers.

Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0
Pragma: no-cache

I am not kind of sure as to whethr it is a cache problem.Because wen a
user clicks on 'Log In',he s redirected to login page.If he has
successfully logged in,requird sessions 'n cookies r set and then
redirected back to referring page.At this point,the referrin page
shows the correct user name from session/cookie.
Wen clickin 'Log Out',the control goes to login function,sessions 'n
cookies r reset and then redirectd back to referrin page.At this
point,the referrin page still shows the username 'n not d logged out
status.Y does d cache comes in2 picture durin log out action 'n not
durin login action?

The login request is submitting a form.

This combination of headers will be honored by most hosts/proxies. In
a situation where it's not, you can try using URL-based sessions or
putting your site under https.

(Top posting fixed - again).

Not necessarily. Some do, some don't. And in some cases it depends on
the browser settings. The same is true with https:.

But this should be discussed in alt.html - this is not a PHP problem.

And again - please don't top post. This group uses bottom posting or
interwoven posting.
