PHP and Internet Explorer

[Jørn Dahl-Stamnes]

Internet Explorer is making me crazy. Things that works OK with FireFox,
does not work properly with IE.

Situation:
PHP script A have a link to a PHP script B. Script B changes some $_SESSION
variables and then do a re-direct back to script A.

With FireFox, the page is refreshed when I click on the link to script B and
the results have be seen. But with IE, the page is not refreshed, so the
changes made due to changes in the session variables, is not visible for
the user. I have to press F5 or click on the Refresh-button in the toolbar
to make the changes visible.

Any hints about what I can do to force a refresh of the page?

Thanks.

Maybe different cache configurations between IE and FF? Not always blame it
on IE. If you need to press F5, then what you're seeing is the cached page,
I think. Review Tools > Internet properties > General > Internet temporary
files > Configuration.

Hope it helps.

No, it did not.
I tired to add:
META http-equiv="Expires" content="-1" (tried other values too)

And it seems to help a bit. But still, sometime it does not update, while it
does it other times... It seems to be more randomly...

Some suggested to add the following text in the pages:
"Looks good inn any serious HTML-browser - this excludes IEx.x"

But that is not a solution.

It is likely due to differences in the way IE reads headers compared to
other browsers... Below is what I have been using for other purposes
that are similar. However, I haven't tested this exact case.

header('Expires : '.gmdate('D, d M Y H:i:s').' GMT');

// USER_AGENT_IE is a constant defined earlier in the script if we could
// tell that the user is (or wants us to think they are) using internet
explorer.
if(USER_AGENT_I E){
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
}else{
header('Pragma: no-cache');
}

I'm sure someone in here is more capable than I to explain all the HTTP
header stuff as I am not an expert in that field by any means...

Re: PHP and Internet Explorer

I don't know if this will help you, but I use this line on each page I
create with sessions:

header("Cache-control: private"); // IE 6 Fix.

No, it seems like if I click on the link and wait before I click on the link
again, IE will reload the new page. But I have to wait at least 1-2
seconds...

Well IE is a problem, if I have a problem with IE and I can not fix it

Re: PHP and Internet Explorer

I found an article on Microsoft's site that may help you with this
issue. I didn't read through all the details to see if it had anything
new that you haven't tried, but hopefully it will have some new
suggestions: http://support.microsoft.com/kb/q234067/
