Hi chanduu4u,
Try this way:
----------------------------------------------------------------->
<% if (Context.User.Identity.IsAuthenticated)
{ %>
<!--- add the live support chat button -->
<script src='<%=ResolveUrl("~/CuteSoft_Client/CuteChat/")%>Support-Image-Button.js.aspx'></script>
<!--- add the live support visitor monitor tag -->
<script src='<%=ResolveUrl("~/CuteSoft_Client/CuteChat/")%>Support-Visitor-monitor.js.aspx'></script>
<% } %>
----------------------------------------------------------------->
