Hey all,

This is kinda neat. I'll forward the link when the proxy-crusher is actually
written.

Actually, certificates certify a common name, or host name, NOT an IP
address. I have successfully used the same cert on multiple physical
servers that were using DNS round robin load balancing.

I specified 'name based virtual hosting' has a problem, not virtual hosting
in general. SSL works fine if you are using IP/PORT based virtual hosting.

Here is the problem with name based virtual hosting and SSL:

The SSL connection is negotiated before the header information is sent, so
the HOST header that is the basis for HTTP 1.1 name based virtual hosting
hasn't come into play yet.

In Apache, if you have multiple name based SSL configuration entries on the
same IP/PORT, the certificate for the first host in the config is
used. That works fine if you are trying to connect to the first
server. If you try to connect to the second server, your browser will
complain that the common name on the certificate does not match the host
name of the URL you were trying to access. That complaint alone is enough
to scare most non-tech people away from trusting the page.
