What version of web gateway are these screen caps from? My block pages aren't nearly as pretty or nifty and I have block page envy.
Umm, I highly customize my block pages and put them in the PreConfig for PoC purposes.
There's this style I've been using for a while, since 7.2.
And a new set i'm working on for 7.4:
And a reduced one for basic error messages for 7.4
I'm sure we could have a long thread discussion on just block pages.
I've been doing it way back since 6.x.
I have a whole portfolio of ones i've done, but they are branded to the customers and would not appropriate for a public forum.
One addition to what's already been said:
The URL filter will also rate embedded URLs (there is a setting to en-/disable that). That means, the URL filter will rate the "forward-url" from google by looking at the domain (google.ca), embedded urls (phdurham.com), and other parameters. Thereby it may come to a different conclusion about the rating than you will get by going to phdurham.com directly.
You could play around with the URL filter settings (e.g. disable the rating of embedded URLs) and see what's best for you.
