Automatic login to a web page

Hi All,

I am new to perl and do not have any idea about this language.

I need your help to solve my problem.

I have internet access on my desktop but each time my machine got
rebooted I need to log-in on
my ISP web's page by providing username,password and submit the button.

Some one told me that we can do this automatically using perl and use
of "LWP::Useragent"
and getcredential () module.

But I do not know perl, If this code is really small, can anyone post
it ..

Or if it takes time to write this then please provide me some from
where I can learn something to write this code.

I know I am fully expecting from others, But I would be really helpfull
if someone can do this for me.

like -- I use this url " http://my_isp_ip_address/indexmail.php"; and
there are only 3 fields.

1 -- text box for username
2 -- text box for password
3 -- "Submit" button

Regards,

.
