I was hoping that someone will respond to this.
I know it is an implementation issue, but should'nt
the sip spec say 2 words about the process of 
computing the request hash - which parameters in
the url should be included .

Thanks,
Shail

When a transaction stateful proxy computes
the hash of the following fields :

Request-uri, From, To, Call-ID and Cseq.number
(maybe even topmost via)

does it include all url parameters of the sip urls
in the above fields ?

So, if the same request visits the proxy as

sip:abcd@proxy
sip:abcd@proxy;maddr=1.2.3.4

and the rest of the fields are same. Is this a loop ?
Don't ask me how this happened. Imagine that there is
one or more misbehaving client/proxy.

Thanks,
Shail
