I tried it and found out it can't work this way - when issuing a CSR with 
getcert, the parameters of this request are normally handed over by getcert to 
the scep-submit helper. I see no way to intercept 
these parameters  and pass them to the proxy-shellscript. Only the -u paramter 
is known beforehand, as it is configured in the ca description file or in the 
proxy shellscript itself.

What are you setting, environment variables I assume?

A quick kludge might be to replace scep-submit with a shell script that exports 
the proxy config and then calls the real scep-submit.

A perhaps better and more supportable idea would be to add a CA pointing to 
this new helper, something like:

getcert add-ca -c exampleSCEPca -e \
     "/usr/libexec/certmonger/scep-submit-proxy -u 
http://ca.example.com/cgi-bin/pkiclient.exe";

So scep-submit-proxy would setup the environment and call scep-submit.
