I have a user enterable link in my application. If the user does not specify the protocol then i want to add http://
by default to it.
eg. if user enters www.google.com
then i want to convert it to http://www.google.com
else if user enters http://www.google.com
... i want to keep it same.
basically i want to modify only those strings and prepend it with http://
if no url is specified.
