# How to use session control

Session control allows you to use a particular proxy IP address for an extended time with multiple requests. You can control your proxy sessions by adding a `sessid-` parameter to your user authentication string, followed by an alphanumeric string of your choice.\
​\
For instance, a complete authentication string would look something like this:

```
customer-USERNAME-sessid-abcde12345:PASSWORD. 
```

We’ve outlined the steps extensively in our documentation. Hence, you can find the links for your acquired Oxylabs product in the list below:

### Dedicated ISP Proxies <a href="#h_e8cdcb0e31" id="h_e8cdcb0e31"></a>

Dedicated ISP Proxies provide fully dedicated IPs with unlimited-duration sessions, meaning each IP is exclusively assigned to you for as long as you need. Instead of using the `sessid` parameter for session control, you access specific IPs directly through their assigned ports (starting from 8001).

To use a particular IP consistently, simply send requests to the same port number. For automatic rotation across your dedicated IP pool, use port 8000.

### Web Unblocker <a href="#h_e631ba9925" id="h_e631ba9925"></a>

In the case of Web Unblocker, the session ID parameter has to be passed as a header, for example, `"X-Oxylabs-Session-Id": "123randomString"`.
