Okay, let me get this straight:
- using browser, when you go to http://www.infojobs.net/empresa_login.cfm,
you're browser shows cookies being sent back
- using LWP, when you go to http://www.infojobs.net/empresa_login.cfm,
no cookies are being sent back
If that's correct, I believe you must all ready have cookies for infojobs.net in
your browser's cookie jar and it's doing something different based because
you come to the page you're sending those cookies. When I go to http://www.infojobs.net/empresa_login.cfm
with my browser (konqueror), I am not presented with any cookies at all.
If you can, copy your browsers cookie to your lwpcookies.txt (being careful
of format and what not).
