The code is

http://pastie....

And i want it to return

nil
www.yahoo.co.in
/~testing/i.html

but when I run this code, why doesn't the www.yahoo.co.in detected?

You might want to play with your regex on Rubular (http://
rubular.com/)
A little experimentation shows that you probably want to include
'http://'
in your input string

the code should work for both, if there's no http:// then it should
print out:

nil
www.yahoo.co.in
/~testing/i.html

if there is then it should print:

http
www.yahoo.co.in
/~testing/i.html

it...
