[Solved] Cannot Read the HTTP Response Header

[Houssam Hamdan]

Greetings,

When the session times out, am adding a key to the HTTP Response Header on the server side. Unfortunately, I did not find a way to read it on Grid client events such as OnDataBinding(). Could you please help me in this ?

Thank you in advance

Hello again,

If it is not possible to read the response header, please recommend an adequate solution when the session times out.

Cheers

Hi Houssam Hamdan,

 The XmlHttpRequest is exposed only in the OnError event of the grid which occurs in case of server-side errors, timeouts etc. You can use that event and perform client-side redirects to the login page when there is a session timeout.

Hi Atanas,

Thank you for the reply.

I can not use your approach because i am handling the session timeout by sending a JSON object as an http response instead. What i need is to get the XmlHttpResponse. Why dont you expose it instead/along with the XmlHttpRequest on client events?

Anyhow, to whom this may concern, I solved it by removing a cookie variable with server side code and then check if that cookie exists on the client side as follows:

Server Side Code:
this.Response.Cookies.Add(new System.Web.HttpCookie("token")
            {
                Expires = DateTime.Now.AddDays(-1),
                Path = "/"
            });

Client Side Code:
 $("div.name").ajaxComplete(function (e) {
        var token = $.cookie('token');
        if (token == null) {          
            alert('Your session has expired.');
        }
    });

Cheers
