What is the difference between http://, https://, and ftp://?

• http://
  HTTP stands for "Hypertext Transfer Protocol". When you (via your browser) send a request that begins with http://, you are specifically requesting a transfer of a file over the internet. Once the file arrives, you will then be able to open and view it on your browser (ex. a website).
  
  
• https://
  HTTPS stands for "Hypertext Transfer Protocol over Secure Socket Layer". This is a web protocol like HTTP, but it sends and receives data that is encrypted. This is often used by banks, etc. who require added security.
  
  
• ftp://
  FTP stands for "File Transfer Protocol". This is a special protocol that is used for exchanging files and commands over a network, such as the internet. This is most commonly used for uploading and downloading files to and from a server.

Unless you have a specific reason to do otherwise, you should use http:// when setting up your web forwarding address.
