Yes!  Couldn't agree more!  Thanx for being very precise.

Okay.  It does sound like we are in total agreement. :-)  If the
Coyote can take care of this,  that'll be great.

So would you be the person to implement this? ;-)

The tomcat 4.0 implementation for the re-handshake assumed that
the handshake is synchrouns.  But I believe the TLS spec says that
this second handshake is asyn.  So to be able to get the certificates
on the socket after the handshake, you'd have to register a
HandshakeCompletedListener...

One word of warning though, it seems that the re-handshake behavior
has changed between JSSE 1.3 extensions to JDK 1.4?  Basically, the
reading of the certificates does not happen unless a read() is
performed.  In other words, after the server initiates the second
handshake, the client certificates will not be read until the server
actually reads something (also true on the client side).

I have already contacted the JSSE team at Sun for verification of
this behavior change and possible workarounds?  I will keep you
updated on that one.

Thanx,
