Authentication for logn and reply

Hi Sreekanth,

We can do this by several ways . for example using Session Variables.I have no knowledge about Session Variable.

I gave a solutions, hope it will help you. If we click a reply button, I think a simple if condition statement will do this.

string returnUrl = Request.QueryString["Username"];

// check Username not null, then consider the user registered
//check Username null, then consider the user not registered
if (returnUrl == null)
{
returnUrl = "~/RegisterUser.aspx";
}
else
{
Response.Redirect("~/Reply.aspx";
}
