Hi,
I don't know how to exactly describe my problem, but I will try my best with
the help of a packet trace.
Below is a trace of an SSL session. As seen from this, when the handshake is
complete, and i send an applicaion data of 128 bytes, why do i get
two record layer packet, instead of just one.
In other wiords, I know how the 152 bytes packet comes, but I have no idea
as to why the client sends an additional 24 byte record layer packet.
Any help is appreciated.
