Question

is there any way to remove session with jquery?
or i use webmethod to remove session (is this good solution?):

$.ajax({
    url: "Default.aspx/RemoveSession",
    type: "POST",
    data: {},
    contentType: "application/json; charset=utf-8",
    dataType: "json"
});

webMethod:

[WebMethod]
public static void RemoveSession()
{
    Session.Remove("UserName"); 
}

Answer 1

Sessions are maintained on server and could not removed on client without sending request to server.

You can do it will ajax call at most or use postback to remove the sessions.
