forward proxy + client certs

[Jeszenszky Zoltán <jeszenszky.zoltan@xxxxxxxxx>]

Hello,

Apache can working as a forward proxy:

SSLProxyEngine on
ProxyRequests On
ProxyVia On
<Proxy *>
# Order Deny,Allow
Allow from all
</Proxy>
ErrorLog /var/log/apache2/proxy-error.log
CustomLog /var/log/apache2/proxy-access.log combined

But can it working as a forward proxy and require client cert?

I want proxy any site but a client certificate would be required. (SSLVerifyClient require) If a user imported own client cert to the browser can use the proxy.
Is it possible? If yes, how can I create the certs and config the forward proxy apache for using client certs?
Using the client cert I think I must SSLEngine on. Is it true?

Thank you.
