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">

<html xmlns="http://www.w3.org/1999/xhtml">

<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>

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?

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" />
