The Rewrite feature allows you to automatically change parts of HTTP Requests and Responses every time they meet a pre-defined set of rules.
This tutorial will show you how to use the Rewrite feature to change the Request and the Response. Please note that you need to compete the Rewrite – Modify the Request tutorial before starting this one.
We are also going to add a simple Regex expression to the Rewrite Rule to allow us target specific data in the Response body. Combining Rewrite Rules with some simple Regex allows you to create incredibly precise and powerful rules.
Prerequisites
This tutorial assumes you have completed a previous tutorial about Rewrite – Modify the Request

Defining the Rewrite Rule
We want to find every instance in the Response body where the “isTailored” property is set to TRUE and then change it’s value to FALSE. The next step will explain how to do this

Create the Rewrite Rule
Click the “Add” button (the one at the bottom of the screen) to open the Rules screen. Configure as follows:
- Select “Body” from the “Type” dropdown
- Untick the “Request” checkbox
- Tick the “Response” checkbox
- Paste “isTailored”:\s*false into the “Match” section’s “Value” textfield
- Also tick the Regex checkbox for the same textfield
- Paste “isTailored”: true into the “Replace” section’s “Value” textfield
- Click OK to save the Rewrite Rule
- Click OK to close the Rewrite Settings screen
