reading javascript cookie

wolverina has asked for the wisdom of the Perl Monks concerning the following question:

I'm using perl to read a javascript cookie. The javascript cookie is created by an html page, and read by a script with a .pl extension. First, can the cookie only be read by the page that created it? Or can a different page read it as long as the path parameters are the same? This code gets internal server error when trying to read a javascript cookie created by another page on the same server, but different directory.

#!/usr/local/bin/perl
use CGI;
$q = new CGI;
$cookie_in = $q->cookie("username"); 
if($cookie_in) 
{ 
   print $cookie_in; 
}  
else 
{ 
  print "Can't find cookie\n";
}

You internal error is caused by your lines `print "Can't find cookie\n";` and `print $cookie_in;` in both the cases where cookie is found or not found. Why? because you didn't `print "Content-type: text/html\n\n";` Add that to your script and the internal server error will go away.	[reply] [d/l] [select]

And since wolverina has already loaded CGI.pm and instantiated an object, that should be: `print $q->header;` [download] jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply] [d/l]
