How to add the client ip in request header in fiddler

Question

I am using fiddler as a reverse proxy, I want to forward the client ip in the request header so that the server can get it like this:

oSession.oRequest["X-Forwarded-For"]=;

But I don't know the variable name that I should set, can anyone help me with this? Thanks a lot.

I found the answer:

oSession.oRequest["X-Forwarded-For"]=oSession.oFlags["X-ClientIP"]
