How can I capture the full header of a cgi script?

[slloyd]

Is there a simle lightweight way to analyze the header of a cgi request? I understand how if I were a server listening on a socket but I cannot think of a way to see the full header from a cgi script. Is there a way?

My favorite methods is wget -S $url on the command line.

There are a lot of ways to do this, but a couple of simple ones are:

- Use the Web Developer add-on / toolbar in Firefox. Under "Information" is a menu option that will display the http response headers.

- Put a print "Content-Type: text/plain\n\n" at the top of your script, before you send any headers. This will display the headers in your web browser (which now thinks they're part of the page content). Of course, you'll need to remove the print statement once you're done debugging.

If you have LWP installed, it comes with the GET utility, which is incredibly useful for just that:

GET -USe http://google.com

You may want to try WWW::Mechanize



#!/usr/bin/perl

use strict;
use warnings;
use WWW::Mechanize;

my $mech = WWW::Mechanize->new();

$mech->get("http://perlmonks.net");

my $headers = $mech->response->headers->as_string;

#!/usr/bin/perl
use warnings;
use strict;
use LWP::UserAgent;
use Data::Dumper;

my $url = 'http://youtube.com/watch?v=2cBVpTRoMjI';

my $ua = LWP::UserAgent->new();
my $result = $ua->head($url);
my $remote_headers = $result->headers;

print Dumper(\$remote_headers);
