BIG-IP : http profile : insert x-forwarded-for : enabled
F5 BIG-IP Virtual Edition v11.4.1 (Build 635.0) LTM on ESXi
HTTP Profile
Insert X-Forwarded-For : Enabled
Suppose the client has already added the "X-Forwarded-For" header value to the request. How will BIG-IP behave ? Will it leave the existing header value intact ? Or will it overwrite the value with what it believes to be the request client ip ?
Further, at what point in request-processing does the insert/replace header operation occur ? Does it occur before iRule processing so that the header value is available within the iRule event processing
when HTTP_REQUEST {}
?
