Hi ,
you can use regularexpression

ASP.NET

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
    ControlToValidate="TextBox1" Display="Dynamic" ErrorMessage="Error"
    ForeColor="#FF3300" SetFocusOnError="True"
    ValidationExpression="http(s)?://([\w-]+\.)+[\w-]+(/[\w- ./?%&amp;=]*)?"
    ValidationGroup="yourgroup"></asp:RegularExpressionValidator>

Best Regards
M.Mitwalli

JavaScript

var s = window.location.host
if(s.indexOf("www.mywebsite.com") == -1)
{
      //the url is not mine so do what need to be done.
}
