## The Repeater

The most used tab in Burp.
Instead of going back to the browser, re-typing the password, and hitting submit... just send the request to **Repeater**.

### Workflow
1.  Right click a request in Proxy History -> **Send to Repeater** (Ctrl+R).
2.  Go to Repeater Tab.
3.  Change one character.
4.  Click **Send**.
5.  Look at the Response on the right.
6.  Repeat.

### Decoder
Hackers use encoding to bypass filters.
*   **Base64**: `admin` -> `YWRtaW4=`.
*   **URL**: `SELECT *` -> `SELECT%20%2A`.
*   Decoder helps you decode cookie values to see if they are readable.
