c# - ASP.NET 3.5 : Allow tilde(~) in URL with the help of regex -

i have text box come in url. there validator set text box check if url entered in textbox valid.

i have used

<asp:regularexpressionvalidator id="valtargetformaturl" runat="server" controltovalidate="txttargeturl" validationexpression="(http|https)://([\w-]+\.)+[\w-]+(/[\w- ./?%&=]*)?" setfocusonerror="true"></asp:regularexpressionvalidator>

the above checks valid url not have special characters in (like ~,%). need look match '~'.

example: need look create ( http://www.domainname.com/~/xyz.pdf ) valid.

(http|https)://([\w-]+\.)+[\w-]+(/[\w- ./?%&=~]*)?

sorry error on part forgot add together ~ in expression
