I have tried all of the options that I can find on the forums but still can't get this to work right in my production environment.

Dev workstation is Windows 7.

Production is Windows 2003 Server.

Web.Config
<system.web>
  <httpHandlers>
    <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" />
  </httpHandlers>
</system.web>

<system.webserver>
  <handlers>
    <add name="ChartImage_axd" verb="*" preCondition="integratedMode" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" />
...
  </handlers>
</system.webserver>

These were added by the Smart Tag.

.ASPX Page
<rad:radchart ID="ticketCountChart" runat="server" DataSourceID="ticketCountChartODS" Height="600px" Skin="Office2007" Width="800px" Visible="False" UseSession="False">
...
</rad:radchart>

~/Temp folder exists and ASPNET has Write permissions.

What am I missing on the production server?

Hello Bradford Stevens,

Are you using the session to store the image (RadChart.UseSession=true) or the filesystem. If using the session have you configured state server or moved session to SQL server? Also, are you using a web farm deployment?

Finally, please install firebug and check the requests to the http handler and what happens there.

All the best,

As stated above in my post, I have configured UseSession=false.

We are using the State Server, not SQL Server, and are not using a Web Farm.

Hi Bradford Stevens,

Unfortunately we haven't been able to reproduce such an issue locally neither have we ever had reports of such a problem. We are not sure what is causing the problem, but in order to investigate can you tell us what is the HTTP server response for the request sent to the HTTP handler?

Greetings,
