Cross Site / Cross Domain Request

About

A request is:

• same-site if its target's URI's origin's registrable domain is an exact match for the request's initiator's (the parent),
• and cross-site otherwise.

A cross site request is also known as:

• a cross website
• or cross domain (What is a Domain?)

Example

• login.example.com and blog.example.com will trigger same-site request because they share the same domain.
