Read easily proxified trafic

edit

I (and probably others) have read your question and could not make full sense of it. Wireshark will show proxied traffic just as well as non-proxied traffic.

If I read your question as if you want to know how to easily match clientside traffic to serverside traffic, then the answer is that there is no general way that requests on the client side can be matched on the server side of the proxy, as the proxy might alter the requests. So that is something you will have to do by hand or by some form of scripting (Lua post-dissector or postprocessing tshark output for example).

If there is anything specific in your traffic that you can make the match with, that would be great, otherwise I'm afraid you will need to do a lot of it manually
