Re: Content Filtering Question

From my understanding of content filtering, unless there is a third party proxy on another server in your network, your Cyber Patrol software is performing this proxy filtering on your machine. This means that the site is downloaded and then parsed for inappropriate keywords. A certain weight of keywords is calculated and the site is displayed or an error message is displayed depending on the
keyword score.I would think that Cyber Patrol installs itself as exactly this, a content filtering proxy server that all users connect through. Therefore, all content unless part of a blacklist
will be downloaded to check to see if the content requested will pass. I hope this helps. Sean Swayze PCSC Information Services On 3-Apr-06, at 3:48 PM, Anton Chekhov wrote:
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512Hie, I downloaded a trial copy of Cyber Patrol. I loaded up ethereal, andthen tried to connect to a page that was blocked(http://www.google.com/search?hl=en&q=guns). When I went back to ethereal I found that the html for the site was sent to the browser, but the browser still displayed a page saying the site was blocked. I was wondering how the software would keep the browser from displaying the page (I'm guessing it works like some sort of extension for firefox) and if that meant that aspecially made browser would display the page. Thanks for any and all help.
