Comprehend CORS - Cross Origin Resource Sharing

Cross Origin Resource Sharing

Understand CORS

Look at the following scenario:

  1. You load website-A
  2. Website A had a script which sends ajax request to website-B
  3. CORS violation appears: The response coming from website-B is blocked by browser from touching data of website-A by default due to CORS policy.

This is a security feature implemented only in browsers which prevents a 3rd party script from extracting your private data and send that to website-B. The gravity of this issue can be understood in the following sample script.
