Yep, but it didn't work out-- I changed the section that defines the user agent to this:
# Create user agent which emulates Internet Explorer
my $ua = LWP::UserAgent->new;
$ua->agent('Mozilla/4.0 (Compatable; MSIE 5.01; Windows NT 5.0)');
$ua->cookie_jar(HTTP::Cookies->new(file => "lwpcookies.txt",
autosave => 1,
ignore_discard => 1));
The msn.com cookies saved to the file just fine (I added the ignore_discard option so it would save session cookies as well). But the InfoJobs site still doesn't show any cookies in the header, and they don't show up in the cookie jar, either.
Thanks for your response, derby
