Don't you hate it when you go to a website at school and find out that the school firewall blocks it? This guide will teach you how to bypass the web filter to access your websites. This may not work on some blockages, whether you use IP or HTML.
If you just type in "https" rather than "http" at the beginning of the address, you can go to some sites, as most blockers aren't configured to block secure web pages. However, some websites just don't work as secure pages.
