This script suppresses the 502 Bad Gateway messages, mitmproxy sends if the server is not responsing correctly.
|
||
|
|
For example, this functionality can be helpful if mitmproxy is used in between a web scanner and a web application.
|
||
|
|
Without this script, if the web application under test crashes, mitmproxy will send 502 Bad Gateway responses.
|
||
|
|
These responses are irritating the web application scanner since they obfuscate the actual problem.
