# No Caching

### 1. What's it?

Prevent the server or client from caching your Request or Response, and you always get the latest change from the server.

No Caching tools will affect all HTTP Request and Response, which enabled SSL Proxying.

### 2. What's for?

* If you would like to **see the latest HTTP Response changes** from the Server or Client and ignore all caching layers

### 3. How it works

No Caching tool will manipulate all requests by adding or removing caching HTTP Headers, which are described in the following table.

| HTTP Message | Remove                                       | Add                                                  |
| ------------ | -------------------------------------------- | ---------------------------------------------------- |
| Request      | **If-Modified-Since** and **If-None-Match**  | **Pragma: no-cache** and **Cache-control: no-cache** |
| Response     | **Expires**, **Last-Modified,** and **ETag** | **Expires: 0** and **Cache-Control: no-cache**       |

### 4. How to use
