Subject Allow SSLProxy* config in <Proxy> context?
Date Wed, 13 Apr 2016 10:40:12 GMT
I stumbled into a situation where a reverse proxy had two different 
backends behind the same VHost of the proxy. Both backends demand client 
certs as becomes more and more common for services today. Unfortunately 
the CA which issues the client certs in both cases is the same CA, but 
the demanded client cert is individual to the backend services.

As far as I can see, this is currently not configurable. The 
SSLProxyMachineCertificateFile and SSLProxyMachineCertificatePath only 
work on the VHost level and the client cert detection algo in 
ssl_callback_proxy_cert() chooses the first client cert it can find 
which was issued b the right CA. No way to distinguish further.

To me it looks like the "right" way of handling SSLProxy* config would 
be per <Proxy>. Did anyone else already encounter a similar problem? Any 
thoughts or experiments on how to solve this for the future?
