I have a site running only with http. I have decided I want to go full https, but I have no idea how to do this.
Do I have to buy that certificate somewhere? Where, how much does it cost?
Does it involve changes in my actual code? Forms, ajax, etc..
Do I have to change something in my server config? What, how, where?
I'm running PHP, I have ftp access to files on server, I can use Parallels environment in browser to change some things on servers...
