I'm in favor of this, since the protocol is only being extended, not really changed.
However, I think that one of the extensions that should be implemented early on is a version negotiation so that the newer side can gracefully degrade in the future without having to rely on the user changing configuration settings. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, November 15, 2001 3:19 PM Subject: Ajp14 and Ajp13 > Hi, > > Right now we treat Ajp13 and 14 as 2 separate workers ( even if most of > the code is shared).
