I have all the variable names figured out.. however Im having trouble assigning a variable name to the submit value. Someone told me not to worry about it and send everything else, but that returned an http 500 error, which signifies the cgi script didnt run. Im thinking thats because it wasnt submitted properly??.. I dont know... heres the code for the lwp program

------------------------------------------------------------
<br> use strict; my $outfile = "result_test.html"; use LWP; my $browser = LWP::UserAgent->new; $browser->cookie_jar( {} ); my $response = $browser->post( 'http://my.screenname.aol.com/_car/login/login.psp', [ "charset" => "iso-8859-1", "siteState" => "", "siteId" => "atlasaol", "newSN" => "0", "mcState" => "initialized", "authLev" => "2", "submitSwitch" => "1", "triedAimAuth" => "y", "screenname" => "kmcp12", "password" => "notmypassword", ] ); die "Error: ", $response->status_line, "\n" unless $response->is_success; open(OUT, "$outfile") || die "Can't write-open $outfile: $!"; binmode(OUT); print OUT $response->content; close(OUT); print "Bytes saved: ", -s $outfile, " in $outfile\n";

--------------------------------------------------------

I dont know what to do about this line from the html source

" <INPUT TYPE="SUBMIT" VALUE="Sign In" tabindex=4>  "

I think thats the problem... Please help.

    There may be more going on in the backend then you can tell. Passing a SUBMIT value won't do you any good, because there is no name="" parameter in the tag, so it won't get passed anyway(at least on most browsers that I've seen).

    Have a look at WWW::Mechanize. It may make this task a little easier.

    Perhaps you should consider posting just a link to the URL http://my.screenname.aol.com/_cqr/login/aimAutoLoginFail.psp?aimWaitCancel=y&triedAimAuth=y instead of posting the HTML source here.

    I think you need to add
    "Sign In" => "SUBMIT"
    to your post command. See if that fixes the problem.

    You're POST'ing to a non-SSL site: http://my.screenname.aol.com/_car/login/login.psp

    Their form posts to an SSL address: ACTION="https://my.screenname.aol.com/_cqr/login/login.psp"

    Do they allow non-SSL logins?
