Can I remove the cookie from a request at the Azure Application Gateway which has a WAF behind it?

Prithvi Kandala 0

We are currently facing an issue with requests being blocked by WAF due to __hp5___meta cookie causing 403 Forbidden Errors._

This cookie is not required in our requests. So, is there a way we can remove it from the requests at the Application Gateway?

Hi Prithvi Kandala,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

In the Application Gateway, you can use the HTTP header rewrite feature. This feature allows you to add, remove, or update HTTP request and response headers as the packets move between the client and backend pools.

Note: The HTTP header and URL rewrite features are only available for the Application Gateway v2 SKU.

Refer this link:

Hope this helps. Do let us know if you any further queries.
