Hi,

I want to redirect to different pages depending whether the user is on a tablet or mobile device, or even at a basic level only redirect mobiles and not tablets. I have 2 things I have setup, but neither does, they redirect all mobiles and tablet.

        Try
            If Session("mobile") = True Or Session("mobile") Is Nothing Then
                Session("mobile") = True
                Dim u As String = Request.ServerVariables("HTTP_USER_AGENT")
                Dim b As New Regex("(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino", RegexOptions.IgnoreCase)
                Dim v As New Regex("1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s\-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|\-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw\-(n|u)|c55\/|capi|ccwa|cdm\-|cell|chtm|cldc|cmd\-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc\-s|devi|dica|dmob|do(c|p)o|ds(12|\-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(\-|_)|g1 u|g560|gene|gf\-5|g\-mo|go(\.w|od)|gr(ad|un)|haie|hcit|hd\-(m|p|t)|hei\-|hi(pt|ta)|hp( i|ip)|hs\-c|ht(c(\-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i\-(20|go|ma)|i230|iac( |\-|\/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |\/)|klon|kpt |kwc\-|kyo(c|k)|le(no|xi)|lg( g|\/(k|l|u)|50|54|\-[a-w])|libw|lynx|m1\-w|m3ga|m50\/|ma(te|ui|xo)|mc(01|21|ca)|m\-cr|me(rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(\-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)\-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|\-([1-8]|c))|phil|pire|pl(ay|uc)|pn\-2|po(ck|rt|se)|prox|psio|pt\-g|qa\-a|qc(07|12|21|32|60|\-[2-7]|i\-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55\/|sa(ge|ma|mm|ms|ny|va)|sc(01|h\-|oo|p\-)|sdk\/|se(c(\-|0|1)|47|mc|nd|ri)|sgh\-|shar|sie(\-|m)|sk\-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h\-|v\-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl\-|tdg\-|tel(i|m)|tim\-|t\-mo|to(pl|sh)|ts(70|m\-|m3|m5)|tx\-9|up(\.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|yas\-|your|zeto|zte\-", RegexOptions.IgnoreCase)
                If b.IsMatch(u) Or v.IsMatch(Left(u, 4)) Then Session("mobile") = True
                If b.IsMatch(u) Or v.IsMatch(Left(u, 4)) Then Response.Redirect("http://www.metoyouonline.com/mobilestore/")
                If Request.Browser.IsMobileDevice Then
                    Response.Redirect("http://www.metoyouonline.com/mobilestore/")
                End If
            Else
            End If
        Catch
            Session("mobile") = True
        Finally
        End Try
        Session("mobile") = Session("mobile")

Open in new window


        If Session("mobile") = True Or Session("mobile") Is Nothing Then
            Session("mobile") = True
            If Request.Browser.IsMobileDevice Then
                Response.Redirect("http://www.metoyouonline.com/mobilestore/")
            End If
        End If
        Session("mobile") = Session("mobile")

Open in new window


Any Help would be appreciatted?

Cheers
Karl

Hi,

There is one more and better approach for redirection is through javascript/jQuery.

This is fastest and most of people using this.

Following js code for detecting iOS devices and redirect, similarly you can use for other mobile/tablet.

<script type="text/javascript"> 
// <![CDATA[
if ((navigator.userAgent.indexOf('iPhone') != -1) || (navigator.userAgent.indexOf('iPod') != -1) || (navigator.userAgent.indexOf('iPad') != -1)) {
document.location = "http://www.scottrockers.com/iphone.html";
} // ]]>
</script>

Open in new window


Hope this helps.

My concern with this is SEO, I was hoping to do it server side for speed and avoid any user viewable redirects?

I also use server side to hold a session for people that want to force view on the main site.
