OCSP / mod_ssl question

Hi,

I noticed when we turn SSLOCSPEnable on, mod_ssl tries to validate the entire certificate chain using OCSP (as the docs already clearly state). Consider the following scenario:

Root CA > Intermediate CA > Client 1
Client 1 OCSP response "good", Intermediate CA has no OCSP URI, validation fails and apache complains.

When using openssl cmd line I can request validation on *just* the client certificate without having a second implicit OCSP request made on the Intermediate CA.

It seems this is done on purpose, but I want to understand better why? Also is it controllable (meaning tell apache only make the OCSP request on the client certificate)?

Any input would be appreciated.

Thanks,
Jeff
