Welcome to the Treehouse Community
Looking to learn something new?
you can watch the Treehouse HTTP course if you don't understand
this is the link: https://teamtreehouse.com/library/http-basics
The course explain the basics of the HTTP protocol. It helps you understand the planning phase.
I suggest to the treehouse staff to insert the course on the teachers note for those like me who dig for the first time into this area.
Thank to treehouse teachers for your wonderful job btw
