What's cross domain.

[dmjpro]

Cross Domain, the web-applications across various machine or built in a same machine

<frame name="firstFrame" src="http://localhost:8084/Domain1/testpage"/>
<frame name="firstFrame" src="http://localhost:8084/Domain2/testpage"/>
 

here are two applications in same machine, so can it be considered as cross domains? Because from the domain1/testpage i can access the elements of domain2/testpage. So are these cross domain?

isn't "localhost" the domain? IMO, domain1 and domain2 are just subdirectories.

@Dormilich
That means the machine should be different ??

See Same origin policy: http://localhost:8084/ is what you look at. They're both the same so it's the same domain.

If you need to test something crossdomain, you can always modify your hosts file, and point another domain like "localhost2" to the same place.. ;)
