Question

Q: I want a regular expression to validate the URL but i wanna to allow this character(~)the Tilda

something like this url:

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

thanks in advance

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.

Answer 1

To allow non-consecutive tildes:

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

To allow tildes anywhere:

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