web mobile application

how to restrict access to a web application just for mobile terminals,( not having access from a pc) thinks

[David Mujica]

I use the following code snipet to determine if a user is visiting my web page from a Blackberry. (the default mobile device supported by my orgainization) I believe this would work to detect any mobile deveice.

If (Request.Headers("X-Wap-Profile").ToString().Length > 0) Then
' This request is coming from a mobile device
End If

Good luck. :thumbsup:

thinks a lot but i'm testing this code:

bool IsMobi = false;

    if (Request.Headers\["X-Wap-Profile"\] != null)
    {
        Response.Redirect("erreur.aspx", true);
      }
    else {
        if (Request.Headers\["X-Wap-Profile"\].ToString().Length > 0)
        {
            IsMobi = true;
            Response.Redirect("login.aspx", true);
        }
        else
        {
            Response.Redirect("erreur.aspx", true);
        }
    }   
   
}}

but he dosen't work correctly, i detect that "Request.Headers["X-Wap-Profile"] != null" is null, i testing from a pda hp and o mobile

Are you sure that Request.Headers["X-Wap-Profile"] returns null, when X-Wap-Profile is not set? Actually, we could expect it to do so, but I'd prefer to include an empty string as a possible return value. Hence, replace

if (Request.Headers["X-Wap-Profile"] != null)

by

if (!string.IsNullOrEmpty(Request.Headers["X-Wap-Profile"]))

thinks for your reply. yes i'm sure that returns null , and also your proposition returns null, this is the code used in my form load:

bool IsMobi = false;

// If request header can find the X-Wap-Profile, then it is a mobile browser
if (!string.IsNullOrEmpty(Request.Headers["X-Wap-Profile"]))
{
if (Request.Headers["X-Wap-Profile"].ToString().Length > 0)
{
IsMobi = true;
Response.Redirect("erreur.aspx", true);
}
else
{
Response.Redirect("login.aspx", true);
}
} }
