Two questions after scheming through the CORS preflight check:
1. Why setting the source origin to the public IP address of the current machine and not to the script origin?

2. Which HTTP methods should actually be checked in advance? GET only? POST? More?
Depending on the particular service implementation of CORS, this initial check may not always be sufficient.
Web apps may anyway need to discover what is authorized by itself.
