Time and again, it must have happened with you that you wish to block web sites under certain niche at your business / work place / home / institution. You may want to do this because of competitive environment of the corporate world or preventing your kids from accessing time-wasters like social networking web sites, video sharing web sites.. or your employees from accessing job searching sites that would affect your business strategy.. What if your competitor hires up your employees for a bit more of money….
It’s very true that you always want to block certain sites at your campus and you may find yourself to be helpless at this.
People have become smart.. Now your silly C:\WINDOWS\system32\drivers\etc\hosts trick will not work.. Do not forget that GOOGLE Chrome has DNS prefetch.
