can two http servers use port 443?

Hi:

We have a web service that is running in its own WAS V6.1.0.0 Express
server that is using an Apache Server listening on port 10026 (see config
below). We also have a WAS 5.1 server which uses a public certificate to
serve data over SSL. this server listens on ports 80 and 443.

We need to configure the first server (the WAS 6.1 server) to serve SSL
connections, and are having trouble getting this to work. My first thought
would be to add port 443 to the Apache config (below) but was not sure
that two servers could listen on the same port.

The error we get is:

IWAB0135E An unexpected error has occurred.
IOException
Unrecognized SSL message, plaintext connection

When we do not use https, it works.

Any advice would be greatly appreciated.

Mike
