Hello!
I run Apache 1.3.19 with mod_ssl 2.8.2 as reverse proxy. This reverse proxy does the
SSL part of the web application. On a specific URL the reverse proxy requests a client
certificate from the browser using this configuration:
<Location /blablabla/>
SSLVerifyClient require
SSLVerifyDepth 1
</Location>
SSLCACertificateFile /blabla/my.CA.crt
This works fine, but the problem is that the application runs on another web server
behind the reverse proxy and that the application needs to know/verify the client
certificate serial number. Therefore somebody (before I started the job here ;-) )
wrote a patch that imports the client certification information into the HTTP header
of the incoming request so that mod_proxy forwards this information to the web server.
Stupid enough this patch is mod_ssl version dependend so I am looking for a nicer
solution. I can imagine that the combination of apache and mod_ssl as a reverse proxy
is very popular and many people have demand on forwarding certificate informations to
the application (web server).
So, is there a nicer solution?
Is this enough reason for adding some configuration parameters into mod_ssl to forward
those informations like
SSLForwardVariable SSL_CLIENT_M_SERIAL
?
