So, I’m trying to intercept a POST request with a content-encoding of application/gzip. Here’s the steps I made:
- Setup Android with an SSL certificate and hook it up as a client on port 3223
mitmproxy -p 3223- Send a POST request with an application/gzip encoded body from the client (Android device) to a server
- The POST request appears on mitmproxy. If I press enter on it, it crashes. Here’s the crash log:
~/Desktop/test » mitmproxy -p 3223 ab@391232

I tried to export the flow but the output had the gzip file and it did not encrypt it.
Mitm proxy output is this
