[squid-users] How to block websites by string or substring

how can i block websites by name or regex?
The block script does not block sites.
I want my own helper, so I can customize
some tasks.
When I start the script in a shell, the file called
"datei.txt" is append texted, if condition is set
to OK.
But squid gives some thing else what I am
oversee at the moment.

In the attachment are the config, the script,
and the mysql data for testing.

Thanks all helping hands.
