Even assuming you're not printing anything before this, it won't work. You're printing two newlines at the end of your Content-type: header. This creates a blank line in your output, and in HTTP, a blank line indicates that headers are over and content begins on the following line. This should cause your Location: line to appear somewhere in the output document, rather than in the HTTP headers.

You shouldn't even need a Content-Type header with Location, anyway.

And, as said before, CGI.pm's redirect() method is a nicer way to do this.
