Same Origin Policy to Web Storage

Local Storage: (Persistent)

• Can be shared between windows with Same Origin
• Remains even after browser window is closed

Session Storage: (Non-Persistent)

• Applies to Active window
• Destroyed after windows is closed

Web Storage follows the same rule of Same Origin Policy. Lets see it in action

Steps:

1. Open Developer Tools
2. Storage
3. Under Local Storage, add Key and Value as shown below. You can also do it via console

1window.localStorage["Token-key-Name"] = "Token-Value"

4. Navigate to Browser Console

1window.localStorage

5. Same way it works for sessionStorage
