Header Location issue with NS4.

[Anon]

I am having an issue with using header location.

On my index page (named index.php) I have a form that allow users to logout and clear their cookies.

The form looks like this:

<form name="form" method="POST" action="index.php">
<input type="submit" name="logout" value="Logout">
</form>

the function for the form is:

if ($logout == "Logout") {

setcookie("user", "", time() - 3600);
header("Location: index.php");
exit;

}

In IE it works fine, but in NS4 I get a Netscape Alert that says "Document contained no data, please try again."
If I refresh the page is NS the user is logged out, so I think it has to do with the header. Any help or is my post too confusing?

Its not a header issue. You are not sending any output to the browser. try this...put in a print statement before the exit. The error will disappear, as there actually is now some readable data being sent to the browser. So your script is working exactly as you have it written, just not as you expected it to.

Netscape Communicator < 6 (and most non-ie browsers) don't like re-directs to the same page (chances for infinite loops). Just change the header() operation to:

header("Location: index.php?"); // note the "?"

and you should be fine.

The problem is the header; the purpose of which is to reload his page. Putting output after the header merely points out the fact that the page is not re-directing to itself.
