SSLVerifyClient for only one directory/vhost

Can I have different SSLVerifyClient capabilities by directory?

[brmiller]

I need SSLVerifyClient optional for one webroot directory and also for one cgi-bin directory.

I need SSLVerifyClient none for another webroot and cgi-bin directory.

I need to have both of these on the same server (same name), as I use a server certificate that has to match the server name.

SSLVerifyClient is not a directory-level configuration directive AFAIK, however, so I'm in a bit of a quandry. I read that it may be possible to set up different virtual hosts (using different directories) using the same server name, but on different ports, but I am not able to follow the myriad of posts, comments, etc. from various google searches well enough to tranlsate them into what I need.

Can anyone point me in the right direction or better yet, give me some sample conf? Another question is that I have configuration in both /etc/httpd/conf/httpd.conf and /etc/httpd/conf.d/ssl.conf (this is a RedHat server). Most of the examples I have seen only make reference to httpd.conf. What, if anything, reads ssl.conf?

BTW, this is for apache 2.
