It works in Firefox, why not in $mech? (aka WWW::Mechanize::Debug) [resend]

Hi everyone,

[Someone just asked me about this, and it looks like the attachment got eaten,
in any case I couldn't find it in an online archive of libwww, so here it is
again in-line.

I have found the attached module to be useful when debugging.
This tells you (I think) what $mech is sending to the server on a click()
operation without needing to resort to tcpdump.

In your code, you'll need

use WWW::Mechanize::Debug;

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

# when you're ready to $mech->click();

print "Request is" . $mech->simulated_click();

Compare this output from what TamperData or LiveHTTPHeaders shows you
when submitting the same request, and chances are, you've found your
problem :-)

Cheers,

Peter
