Hello all

Often I see OS renaming files like "This Is A File
Name" to "This%20Is%20A%20File%20Name"

or, web browsers changing "ftp://somesite"; to
"ftp:%2f%2fsomesite"

On careful examination, it's evident that the
characters like "/" (forward slash) or " "
(whitespace) are being replaced by a '%' sign followed
by their equivalent ASCII hexcode.

For example :

"/" -> %2f
" " (whitespace) -> %20

etc.

I want to know WHAT these sequences like "%20" or
"%2f" are called.
Can anyone point me to furthur information ?

Regards

Subhobroto Sinha
