Adding an auto response from file feature

Rami | Last updated: Jul 07, 2021 01:02PM UTC

Hi, In fiddler, there is a feature called AutoResponder which allows setting a rule for a specific URL. If the rule matches, the file content set in the rule will be provided in the response instead of the original response. Is it possible to add a feature like this to Burp? Thanks.

Thanks for the feedback. You do have the option to automatically replace parts of the requests and responses that are being intercepted under Proxy -> Options -> Match and Replace. Can you send us an example of the kind of change you'd like to make to help us understand the full use case? Feel free to either email it to support@portswigger.net or post it here.

I have modified a javascript from HTTP response. E.g. adding console.log in functions I would like the Fiddler feature called AutoResponder which replace the response when rule is matched E.g. When hit http://localhost/example.min.js, load my c:\development\example.js for http response I would suggest you to explorer the Fiddler's AutoResponder feature which is very useful.
