client certs will only work when you pass the connection directly to web
server without unbundling SSL.
That means, it's useless to use reverse proxy for HTTPS server when it needs
client certificates.

The workaround you could be in verifying client certificates by squid,
pushing that info to server and webserver trusting that info...
