[squid-dev] Block users dynamically

[dean]

I am implementing modifications to Squid 3.5.27 for a thesis job. At 
some point in the code, I need to block a user. What I'm doing is 
writing to an external file that is used in the configuration, like 
Squish does. But it does not block the user, however when I reconfigure 
Squid if it blocks it. Is there something I do not know? When I change 
the file, should I reconfigure Squid? Is there another way to block 
users dynamically from the Squid code?
