Hi, it's just better to keep the thread in the maillist.

That's not true. The request can contain a header like:

 TimeStamp: 25

and the proxy/server replies in the 100 Trying:

 TimeStamp: 25 0.001


This means that it has token 0.001 seconds to the server in order to
process the request and generate the 100 response.
