I have the following settings

 

1. web.config

        <system.web.extensions >
<scripting ><webServices/>

<scriptResourceHandler
       enableCompression="true"
       enableCaching="true" />
</scripting >

</system.web.extensions >

 

2. compilation debug = false in web.config and master page

 

3. <telerik:RadScriptManager ID="ScriptManager" runat="server" ScriptMode="Release" EnableScriptCombine="false" CacheSettings-Enabled="true" /> in master page.

However if i enable cdn, cdn is able to server 304, I assume it is because the files are static in the CDN.


Can Telerik support advise howw to make axd return 304?

 

 

Thanks.

Hi,

Use CDN's:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<head runat="server">
    <title></title>
    <telerik:RadStyleSheetManager runat="server" CdnSettings-TelerikCdn="Auto"></telerik:RadStyleSheetManager>
</head>
<body>
    <form id="form1" runat="server">
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnableCdn="true" >
        </telerik:RadScriptManager>
        <telerik:RadComboBox runat="server"></telerik:RadComboBox>
        <script type="text/javascript">
        </script>
    </form>
</body>
</html>

or define required scripts in the script manager:
<telerik:RadScriptManager runat="server" EnableCdn="true" EnableEmbeddedjQuery="false">
        <Scripts>          
            <%--To learn more about bundling scripts in ScriptManager see http://go.microsoft.com/fwlink/?LinkID=272931&clcid=0x409 --%>
            <%--Framework scripts--%>
            <asp:ScriptReference Name="MsAjaxBundle" />
              
            <asp:ScriptReference Name="jquery" />
              
            <asp:ScriptReference Name="WebForms.js" Assembly="System.Web" Path="~/Scripts/WebForms/WebForms.js" />
            <asp:ScriptReference Name="WebUIValidation.js" Assembly="System.Web" Path="~/Scripts/WebForms/WebUIValidation.js" />
            <asp:ScriptReference Name="MenuStandards.js" Assembly="System.Web" Path="~/Scripts/WebForms/MenuStandards.js" />
            <asp:ScriptReference Name="GridView.js" Assembly="System.Web" Path="~/Scripts/WebForms/GridView.js" />
            <asp:ScriptReference Name="DetailsView.js" Assembly="System.Web" Path="~/Scripts/WebForms/DetailsView.js" />
            <asp:ScriptReference Name="TreeView.js" Assembly="System.Web" Path="~/Scripts/WebForms/TreeView.js" />
            <asp:ScriptReference Name="WebParts.js" Assembly="System.Web" Path="~/Scripts/WebForms/WebParts.js" />
            <asp:ScriptReference Name="Focus.js" Assembly="System.Web" Path="~/Scripts/WebForms/Focus.js" />
            <asp:ScriptReference Name="WebFormsBundle" />
            <%--Site scripts--%>
        </Scripts>
    </telerik:RadScriptManager>

Any response, what is CDN is not possible and I want it to cache within internal network. It does not seem to be working correctly.

You can setup a local CDN in your internal network: Custom CDN Provider

Please correct me if my understanding is wrong, it seems the AXD is not correctly returning a correct status code which seems to me is a bug....and the suggestion is to do all this legwork to setup a "mini/localised" CDN as workaround?

This is how the asp.net works. Try to set:
<compilation debug="true" targetFramework="4.0"/>

For more information please read this article: http://weblogs.asp.net/scottgu/442448

I have tried that and it seems it does not work. Please see attached images.

 

<compilation debug="false" targetFramework="4.0">
 
 
<telerik:RadScriptManager ID="ScriptManager" runat="server" ScriptMode="Release" EnableScriptCombine="false" CacheSettings-Enabled="true"  />
<telerik:RadStyleSheetManager ID="RadStyleSheetManager1" runat="server" EnableStyleSheetCombine="false" />

 

 

<add key="Telerik.ScriptManager.TelerikCdn" value="Enabled" />
        <add key="Telerik.StyleSheetManager.TelerikCdn" value="Enabled" />
