Once surfing the Internet I came across one interesting page. Text was not singled out. The browser didn't also react to the clicks of the right mouse button. Nothing really happened. At the beginning of the text on a green background there were proud words "The source code of this page is protected by HTML Guardian".
I didn't understand the staff and tried to see page source. Oops! File empty. But it was empty at the first sight. The text was displaced on a few screens downward. Trick for nuts. I pushed DEL-key and in a few seconds the situation was all right. I saw the following: "The source code of this page is encrypted with HTML Guardian, the world's standart for website protection. Visit http://www.protware.com for details." Yes STANDART :)
Well well, I think and go to the link.
