[squid-users] Ssl-Bump and revoked server certificates

Good catch - I don't think squid does CRL/OCSP checks

I'm using the external_acl_type method to achieve that: it does the
extra work and returns "ERR" for revoked certs - which (for me) causes
squid to fallback on splice mode - so that the client browser can see
the actual fault directly (ie I'm making sure revoked certs are never
bumped)

But this is a bug in squid - this means untrustworthy certs become
trusted again - not a good look
