How it Works

Web Safety is very simple to deploy and use. The administrator needs to deploy it within the network and configure client browsers to use the appliance as a proxy. Then the following sequence of event occur:

1. User tries to navigate to a given web page by typing web site address in the browser address bar.

2. Browser sends a request to Web Safety appliance. This request gets intercepted by Squid proxy running on the appliance.

3. Squid proxy process connects to the remote site, downloads a page and sends its contents to ICAP web filter process running on the same appliance.

4. ICAP web filter checks the inner contents of the page and blocks the access or allows it.

5. Browser renders the allowed response and/or shows a denied page informing the user of a prohibited URL.
