How Server respond when AJAX Request to the Server While one AJAX Request in Progress

Note: In my past Experience i got the scenario when one AJAX server request in Process then other AJAX request is given to server. 

Now Question arise that what will happen in that case?

Ans :- In that Case 1st one request will stopped and 2nd Request will be initialized to server on that time.

You can check with Your Self with given below Steps:

Step 1: Make AJAX Web based project and put the given below Code in body Tag of Default.aspx file.

<form id="form1" runat="server">

        <asp:ScriptManager ID="ScriptManager1" runat="server" />

    <div>

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">

    <ContentTemplate>

        <asp:Button runat="server" Text="Button" ID ="Btn" OnClick="Btn_Click"/>

        <asp:Label runat="server" Text="Label" ID ="Lbl"></asp:Label>

    </ContentTemplate>

    </asp:UpdatePanel>

        <asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">

            <ProgressTemplate>

            <asp:Label runat="server" Text="Please Wait while work in Process......" ID="Lbl2"></asp:Label>

            </ProgressTemplate>

        </asp:UpdateProgress>

    </div>

   

   

   

    <div>

    <asp:UpdatePanel ID="UpdatePanel2" runat="server">

    <ContentTemplate>

        <asp:Button runat="server" Text="Button" ID ="Button1" OnClick="Button1_Click"/>

        <asp:Label runat="server" Text="Label" ID ="Label1"></asp:Label>

    </ContentTemplate>

    </asp:UpdatePanel>

        <asp:UpdateProgress ID="UpdateProgress2" runat="server" AssociatedUpdatePanelID="UpdatePanel2">

            <ProgressTemplate>

            <asp:Label ID="Label2" runat="server" Text="Please Wait while work 2 in Process......"></asp:Label>

            </ProgressTemplate>

        </asp:UpdateProgress>

    </div>

   

    </form>

And put the given below code in Default.cs File.

protected void Btn_Click(object sender, EventArgs e)

    {

        System.Threading.Thread.Sleep(10000);

        Lbl.Text = "This is First Ajax";

    }

    protected void Button1_Click(object sender, EventArgs e)

    {

        //System.Threading.Thread.Sleep(10000);

        Label1.Text = "This is Second Ajax";

    }

 

• First Button Click Response with Update Progress

 

• On the Same time Click on Second Button then First one is Stopped and Second Request is initialized see below output Screen shot:
