Session and headers - for experts -

cubax

Hello everybody,
I have a problem which is getting me crazy.
I have an application in which I serve files to users with these 3 rows using headers:

header('Content-Type: application/save');
header('Content-Disposition: attachment; filename=$flName');
readfile($file);

In this way everything is fine bot with NS and IE.
The problem comes with the sessions.
As I need to use sessions, my script starts with

session_start();

Well, in this way It only works with NS and not anymore with IE.
Did anybody of you ever have such a problem?
Ideas?
Many thanks in advance.

Hi Alessandro

I'm no expert, but I can confirm that session_start() works fine with IE and indeed with Firefox and Konqueror and anything else you care to mention. I have some webpages which use sessions and I tested them all with IE. There must be another problem lurking somewhere.

Sorry - I don't know the answer, but I'm sure it's not a browser problem.

Hi,

try this one:

<?PHP
session_start();
// some other code

header("Cache-Control: Public");
header('Content-Type: application/save'); 
header('Content-Disposition: attachment; filename=$flName'); 
readfile($file); 
exit;

Add the Cache-Control directive. Try Private instead of Public if that doesn't work.

Seems to be a problem with at least IE 5.5

Norman,
it HAS something to do with the browser... Not the function
session_start() itself... But the combination of session_start() with the way I use to serve files to users.
...Of course I use session_start in all my scripts and it works fine...

I confirm that with Mozilla, NS, Konqueror and whatever it works fine but not with IE where when trying to serve the file the user gets an error like "page cannot be retrieved".

Tsinka,
I tried what you mentionned and it returns the same error.

I really think that we should have to work with session commands instead of focusing on headers....

PLs help!!! 😉
