school internet filter bypass
How to use web recorders work?
Our chemistry teacher do what he wanted with all that was available chemicals for a project this year. Naturally, everyone wants to do something explosive. Therefore, let all the teams and enter the proxy to bypass the Bess filtering software in school because they do not think this would be appreciated. Anyway, the next day, we see that our teacher was boring because the Board determined that one of our students I was looking at a site called "Terrorist" to search for explosives manual. We have found that Google's cache used to bypass the filter. My question is, how it does not occur when using proxy servers for real? The URL is still HTTP request when using a proxy server, the only major difference is where it sends the application. Like all Internet traffic passes through the school server first, then the Board of Ed, even going through the filter and recording when using proxy servers. Then why did my friend get busted, while others do not?
If you use Google to go and see the cached page that has the images, the page retrieves the images from the original site unless you use the proper voodoo [1] to tell Google not to get pictures of everything. Thus that, had marked the site, probably noticed the image URL of your friend to be read directly, while yours were made indirectly (send a request to the connection with the proxy, and then choose Web page). The traffic officer can not be looking at the contents of all packages, only the initial URL is retrieved. [1] If copy the URL of the cached page of Google Search and paste in a new window and add "& strip = 1" (without quotes) to the, Google offers cached page without images.
