I was attempting to create an ON/OFF switch for a cyber-cafe; so that the staff could allow/disallow Internet access (based on if they had paid or not).
Using the directions on chaining from http://cs.zip.com.au/adzap/#chaining created a quick perl-script which checked for a file on a ram-disk, if the file was missing then the perl script redirected to the user to a RESTRICTED page. Otherwise the request went to squidGuard. The script was just "if file exists echo original url else echo restricted page url" Locally testing everything seemed fine, and even after I deployed it, everything was fine for a while- then there was a performance hit (I wasn't there physically to check things out), so I rolled back to an un-chained squidGuard. Things seemed fine. I'm not ruling out the possibility of a glitch with the ISP. Does anyone know of any tools to simulate (lots of clients), to just keep hitting web-pages. This isn't going to be on a huge scale - only have 256Kb of bandwidth and 4 machines. Regards, Adam
