URGENT: libwww-perl: automated form filling

[Alberto Maurizi <alberto@sif.it>]

	Hi all, Debian people.

	I'm quite new to perl and, in particular to libwww-perl.
	I fell on it because I was looking for some API to write
	www clients to automatically fill forms.

	The problem I have is that I cannot get the same result from
	the server as I obtain using a web browser. What happens is
	that the result is the same document I use as HTTP::Request while,
	if I use a web browser, clicking the submit button I get 
	a "second" document.

	Does anybody know/understand the problem?
	Where to find source of information/examples?
	Is there any better solution than libwww-perl?
	(note that the problem persists using "lynx -post_data")

	Thanks in advance,
	Alberto Maurizi
