How to intercept and modify plain http?

Question

Computer networks

There is an exchange of plain http traffic between the two servers. The POST request body contains a list of file paths. Task: intercept the request, modify some of the links in the request body and pass the traffic on. Maybe some reverse proxies can do this?

Answer 1

If you need to implement a MitM - Intercepter-NG attack (without access to servers)
If you have access - you can use an intercepting proxy, Burp Intruder definitely knows how, OWASP ZAP most likely too, but I'm not sure if it will be possible to set a proxy in the servers and work with him correctly.
That Burp, that Intercepter-NG can do this automatically (replacement).
