How to Change Redirect Destinations using Response Rewrite Rules in NSX LB

Products

• VMware NSX

Issue/Introduction

• Web servers may use the Location field in HTTP responses to redirect clients to a specific destination.
• This article describes how to rewrite the redirect URL using Response Rewrite Load Balancer Rules in NSX LB.

Environment

VMware NSX

Resolution

• To create a Response Rewrite Load Balancer Rule in the NSX native load balancer, navigate to Networking > Load Balancing > Virtual Servers in the NSX Manager.

• Add a rule under the Response Rewrite Phase of the target Virtual Server as follows:

  •   Match Condition
    Condition： HTTP Response Header
    Header Name: Location
    Match Type： any value
    Header Value： any value

  •  Action
    Action： HTTP Response Header Rewrite
    Header Name： Location
    Header Value： any value

In this configuration example, the NSX LB overwrites the Location header to https://example.org/example.html only when the web server responds with https://example.com/example.html.

 

Additional Information

Redirect destinations can also be configured within the Application Profile.
