Problem with CGI Cookies and Redirects

[Chris Haupt]

We have a script using the CGI module which sets a cookie and then
performs a redirect:
print $q->redirect($url, -cookie=>$cookie) ;

In version 2.81 of CGI this works fine. When we upgraded to 3.05
recently this stopped working. In Explorer when I run this script I
get the following error:
Internet Explorer doesn't know how to handle the type of file you have
selected

You can choose to save this file to your disk or you can configure a
Helper Application for this file.

MIME TYPE: application/x-httpd-cgi
File Name: goto.cgi

Using the cookie in the header function (e.g. print $q->header(
-cookie=>$cookie)) works fine in 3.05 so the problem appears to be
with the use of cookies in the redirect method.

We've backed up to version 2.81 but I'd like to get back to 3.05 if
this problem can be resolved.

Thanks,

Chris

I did a couple tests using CGI.pm 3.01 but I found something that might be of interest assuming it also happens in 3.05.

Using this code-line:
print $q->redirect(-uri => $url, -cookie => $cookie);

the output on the command-line is:
-->./redirect.pl
Status: 302 Moved
Set-Cookie: redirectTest=redirectValue; path=/; expires=Sat, 19-Jun-2004 01:22:4

Using this code-line (from OP's post):
print $q->redirect($url, -cookie => $cookie);

the output on the command-line is:
-->./redirect.pl
Status: 302 Moved
Window-Target: -cookie
Set-Cookie: redirectTest=redirectValue; path=/; expires=Sat, 19-Jun-2004 01:24:0

Notice the 'Window-Target' header line. Doesn't seem like this would cause the error you mentioned but I figured I'd mention it.

Try this:

print $q->redirect(-location=>$url, -cookie=>$cookie);
-----------------------^^^^^^^^^^^

Even if it requires some guesswork, it appears as if you need to state
the -location parameter explicitly when you use CGI.pm's redirect()
method for printing other headers.
