Hi Filip,

 

Fiddler acts as a MITM web proxy meaning that it will serve as a man-in-the-middle proxy that captures incoming and outgoing traffic through HTTP and HTTPS protocols. You could use it to mock server responses and see the result locally without having modified the server. You could also make custom requests to capture and inspect the generated traffic from browsers and any other applications that are using HTTP and HTTPS.

I am not aware of the technology stack used for the creation of League of Legends, but if it uses HTTPS, you could probably mock some of the responses for local testing. It won't change the operations made by the game server (unless you modify the requests and the server is OK with the modified content).

Something else I've wanted to add. It appears that League of Legends is most likely using a certificate pinning which means that the server expects a specific certificate to trust the client - a security setting made primarily to prevent MITM manipulations. If that is the case, then there is not much you could do with

Thanks for the explanation, the https protocol is different from http, when I remove the https protocol it still leads to my link as usual. For example, this venge io game is similar to league of legends it uses https protocol but its address does not change when accessing with http protocol
