no problem, it is good code :-)

Have you or R U looking into or using IO::Socket::SSL ??
There might be a method in there to do what U want.

you could play with IO::Socket to emulate this, but I don't think it will
make much of a difference.

well, there are other ways, but I don't know about better. If it works and
the performance is not a hinderance ..no need to fix it.

I don't think so. I use them quite often and rarely do I have to take em out
because of performance.
