I meant the definition in RFC2616

"A "transparent proxy" is a proxy that does not modify the request or 
response beyond what is required for proxy authentication and 
identification"

But intercepting proxies are another kettle of fish again.

I think the para at the start defining proxy states that unless there's 
wording specifically relating to requirements for transparent or 
non-transparent proxies, then the wording applies to both.

Which then answers my question, since there's no mention of transparent 
or non-transparent in the clause for Via, one should assume it applies 
to both, which means a transparent proxy must also insert Via, which 
then leaves one wondering about the definition of it (unless we consider 
that Via is a function of identification?)
