Michael,
   
  It works!! Thank you very much. What does 2>&1 do though? I'm just very curious.
  Oh, one more thing that I didn't get to mention and I think that you might know. I'm unable to just use "curl -v https://... ", it'll prompt a message window saying "curl.exe has encountered a problem and needs to close." So I have to force it to use SSLv3 by doing "curl -v -3 https://...", but the output displays both SSL certificate information and HTML code which is not exactly what I need. I just want to get the certificate information. Do you know why and how to fix it?
   
  Thank you very much for your help,
   
  Santi

Probably because messages go to stderr? Try `curl -v ... 2>&1`
