If the original request spiralled, and the proxy inserted
a R-R on each iteration of the spiral, every subsequent request in
the dialog would also spiral through. Let me illustrate what i am
with an example. If my understanding is incorrect on some account,
please correct me.
Consider the foll. scenario where a request spirals through a proxy P1 :
[EMAIL PROTECTED] --> P1 --> P2 --> P1 --> P3 --> [EMAIL PROTECTED]
The Route set constructed at B will be:
Route: [EMAIL PROTECTED]; maddr=P3
Route: [EMAIL PROTECTED]; maddr=P1
Route: [EMAIL PROTECTED]; maddr=P2
Route: [EMAIL PROTECTED]; maddr=P1
Now, every subsequent request in the dialog (from B) will also spiral.
But since P1 inserted unique URI's in each iteration, it would receive
different Request-URI's and hence understand it to be a spiral.
Let me know if i am missing something.
Thanks,
Subhash Nayak.
