Why session id changes every time in ASP.NET?

Why session id changes every time in ASP.NET?

protected void Session_Start(Object sender, EventArgs e) 
{
    Session["init"] = 0;
}

http://msdn.microsoft.com/en-ca/library/system.web.sessionstate.httpsessionstate.sessionid.aspx
a new session ID is generated for each page request until the session object is accessed. If your application requires a static session ID for the entire session, you can either implement the Session_Start method in the application's Global.asax file and store data in the Session object to fix the session ID, or you can use code in another part of your application to explicitly store data in the Session object.

            //Get the assembly that contains the internal class
            Assembly aNetAssembly = Assembly.GetAssembly(typeof(System.Net.Configuration.SettingsSection));
            if (aNetAssembly != null)
            {
                //Use the assembly in order to get the internal type for the internal class
                Type aSettingsType = aNetAssembly.GetType("System.Net.Configuration.SettingsSectionInternal");
                if (aSettingsType != null)
                {
                    //Use the internal static property to get an instance of the internal settings class.
                    //If the static instance isn't created allready the property will create it for us.
                    object anInstance = aSettingsType.InvokeMember("Section",
                      BindingFlags.Static | BindingFlags.GetProperty | BindingFlags.NonPublic, null, null, new object[] { });
                    if (anInstance != null)
                    {
                        //Locate the private bool field that tells the framework is unsafe header parsing should be allowed or not
                        FieldInfo aUseUnsafeHeaderParsing = aSettingsType.GetField("useUnsafeHeaderParsing", BindingFlags.NonPublic | BindingFlags.Instance);
                        if (aUseUnsafeHeaderParsing != null)
                        {
                            aUseUnsafeHeaderParsing.SetValue(anInstance, true);
                            return true;
                        }

Web design trends

Single page websites

Once frowned upon by both clients and designers, long pages which require a lot of scrolling are now all over the web. One explanation is that users are so accustomed to vertical scrolling (assisted by mouse wheel) that it’s actually worse to split the content on separate pages – it requires more effort from users to find it and reach it.

 

Google Architecture

Update 2: Sorting 1 PB with MapReduce. PB is not peanut-butter-and-jelly misspelled. It's 1 petabyte or 1000 terabytes or 1,000,000 gigabytes. It took six hours and two minutes to sort 1PB (10 trillion 100-byte records) on 4,000 computers and the results were replicated thrice on 48,000 disks.
Update: Greg Linden points to a new Google article MapReduce: simplified data processing on large clusters. Some interesting stats: 100k MapReduce jobs are executed each day; more than 20 petabytes of data are processed per day; more than 10k MapReduce programs have been implemented; machines are dual processor with gigabit ethernet and 4-8 GB of memory.
