# Configuring the Non-Caching A/B Testing Integration

## Adding the session id parameter

**‌**In order to request a variant of a given FHR page, all you need to do is supply one extra parameter to the FHR query - **fh\_session\_id**. With that parameter you specify the session ID of the user requesting the page which should be the same as the one used in CADP tracker integration . This session ID should be generated on the server side and then passed in **all FAS queries** as well as to the **CADP tracker.** An example of how the user’s session ID parameter would look in the request can be seen below:

`fh_session_id=123e4567-e89b-12d3-a456-426614174000`

After you add the parameter you are all set to receive the appropriate A/B test variants for the requested page.
