Auto-Resend Requests in proxy

Björn | Last updated: Apr 23, 2021 04:00PM UTC

Hi, I have a web site that uses captchas during heavy load. It’s problematic since it’s JavaScript code is silently failing when sich a captcha is retrieved in a HTTP response. Captchas are not visible, so I’d like to intercept the response with an condition (that works already), but then automatically have it resend, with the new response handed to the original request. This should already fix it, since these captchas only show each 5th request or so. I was wondering if any default function or extension exists for this, but didn’t find anything alike. Cheers

To explain it easier: I would like to automate: - intercept response - action-> send to repeater - resend request in repeater - copy response from repeater to proxy - forward response in proxy

Hi

Are you using Burp Suite Professional, Community, or Enterprise edition?

If you are using Professional or Community this sounds like it could be an opportunity to implement a session handling rule.

This can be found under "Project options > Sessions > Session handling rules".

Further details on session handling rules can be found here.
