What is Mean by Cross-Origins and Same-Origins? | HTTP Interview Question

Two URLs have the same origin if they have identical schemes, hosts, and ports. (RFC 6454)

These two URLs have the same origin:

• http://example.com/foo.html
• http://example.com/bar.html

These URLs have different origins than the previous two:

• http://example.net - Different domain
• http://example.com:9000/foo.html - Different port
• https://example.com/foo.html - Different scheme
• http://www.example.com/foo.html - Different subdomain

Internet Explorer does not consider the port when comparing origins.
