Don, they mention Web servers in the definition of what a "named user" is and where you should mesure how many users are connecting. See the last paragraph from my previous post.
I think that the licensing is still a little bit confusing, but for a webserver, you should always go to the "processor based" license, I guess, since the named user "MINIMUM" that you have to buy is just that, the "MINIMUM" and then you have to add ALL the possible users (one per license) that would connect to your webserver (even non-human programs or devices).
I am not a license-freak, nor a lawyer, so please double-check every thing with Oracle sales rep and your legal dept 😉.
As Don correctly points out, PostgreSQL rocks for most of the sites.
