Rewrite HTTP headers with Azure Application Gateway

Rewriting HTTP headers in Azure Application Gateway is now supported. You can add, remove or update HTTP request and response headers while the request and response packets move between the client and backend application. You can also add conditions to ensure that the headers you specify are only rewritten when the conditions are met. Rewriting headers helps you accomplish several important scenarios such as removing port information from X-Forwarded-For headers, adding security-related header fields such as HSTS/ X-XSS-Protection, removing response header fields which may reveal sensitive information etc. For more details, please see <https://aka.ms/HeaderRewriteInfo> * Application Gateway * Features * [ Application Gateway](https://azure.microsoft.com/en-gb/products/application-gateway/)
