something like this url:

http://stackoverflow.com/questions/~/ allowing http or without http

EDIT:

i find a perfect one finally: (http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&:/~\+#]*[\w\-\@?^=%&/~\+#])? but i wanna to allow the user to enter the url with the protocol or without it to prevent any confusion how to do that.

There is a very good regular expressions site here where you can get almost any regular expressions. Think this would be useful to you.

I'm not sure what do u want. But 

\w+([~'\.]\w+)+

Valid for

justname'com
just_name~com
justname.com

Invalid for

justname
just-name-com

If you use 

\w+([~]?)\w+\.\w+

Valid for

justname.com
just~name.com

Invalid for

justname'com
just_name~com
just-name-com

To allow non-consecutive tildes:

\w+([-+.'~]\w+)*

To allow tildes anywhere:

[\w~]+([-+.'][\w~]+)*

you can try with this one:

\b(https?|ftp|file)://[-A-Z0-9+&@#/%?=~_|$!:,.;]*[A-Z0-9+&@#/%=~_|$]

if you don't need the HTTP,FTP... youc an take it off like:

\b[-A-Z0-9+&@#/%?=~_|$!:,.;]*[A-Z0-9+&@#/%=~_|$]
