Redirect with no referer...

[Erik Rull]

Hi,

I wrote a webmailer and want to "derefer" links that are clicked within
mails, so that no session or any other param are in the referer-field of
the target server.

I had this attempt:

#!/usr/bin/perl

print "Refresh:1;URL=http://www.server.to/click.on\n\n";

But the referer is only killed in some browsers, some versions of the
MSIE still take the referer with.
Bug or feature? ;-)

Any other ideas?

Greets,

Erik

If you are having trouble with Perl's print() function then
you have a Perl question.

Are you having trouble with Perl's print() function?

Ask Perl questions in a Perl newsgroup.

Ask web questions (like yours) in a web newsgroup.

You can't control the refer header cause it's sent by the browser.

Instead you could use LWP:Simple to act as a proxy. You send exactly the
headers you want the remote site to see.

Then your script receives the results and sends them back to the browser.

Hopefully the html from the remote site has embedded links that point back
to their own site so that the browser sends subsequent requests to that
site, and not back to your script. I guess you could parse the html
before you send it back to ensure there is a base statement to the remote
site to help make relative links work.
