Hi Juha, Yes, I understand that the proxy doesn't need to care. That's absolutely correct. In fact, it should be the most common scenario.
I think the point is that some proxies WANT to know. They want to use the keep-alive to keep tract of the availability of the UA without waiting for a request to fail. I don't want to debate if this is a good idea or not, but I believe this is why they want this. > -----Original Message----- > From: Juha Heinanen [mailto:[EMAIL PROTECTED] > Sent: Thursday, May 08, 2008 08:54 > To: Audet, Francois (SC100:3055) > Cc: Christer Holmberg; Jiri Kuthan; [email protected] > Subject: RE: [Sip] Draft: draft-holmberg-sip-keep-00.txt > > Francois Audet writes: > > > It will know because the UA send double-crlf.
