error 404.0 when showing rad chart image in IIS7

[mansour]

Hello,
   I have an application which is working well under IIS6, but when I am using it under IIS7, in the page that has rad chart, I am getting this error:

HTTP Error 404.0 - Not Found

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

Detailed Error Information

Module	IIS Web Core
Notification	MapRequestHandler
Handler	StaticFile
Error Code	0x80070002

Requested URL	http://localhost:80/smarTrend/EnterprisePages/ChartImage.axd?UseSession=true&ChartID=b40fd0b5-683d-4efc-acce-8460a749ebdf_chart_ctl00$BodyContentPlaceHolder$LowerChart&imageFormat=Jpeg&random=0.786466626816646
Physical Path	C:\MyWorks\SmarTrend\EnterprisePages\ChartImage.axd
Logon Method	Anonymous
Logon User	Anonymous

Most likely causes:

• The directory or file specified does not exist on the Web server.
• The URL contains a typographical error.
• A custom filter or module, such as URLScan, restricts access to the file.

Things you can try:

• Create the content on the Web server.
• Review the browser URL.
• Create a tracing rule to track failed requests for this HTTP status code and see which module is calling SetStatus. For more information about creating a tracing rule for failed requests, click here.

I have the correct http handler in my web.config:

<

 

add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI, Version=2008.2.826.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>

add path="Telerik.Web.UI.SpellCheckHandler.axd" verb="*" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI, Version=2008.2.826.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>

add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2008.2.826.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>

add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2008.2.826.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>

Could somebody help me to find what is the problem?

Best regards

Hello mansour,

Please review the following troubleshooting section here -- when in Integrated mode, IIS7 reads the application configuration from the <system.webServer> section group in the application configuration file, but not the <system.web> section group.

Let’s suppose you have the following structure of the web.config file:

<system.web>

…

      <httpHandlers>

            … 

<add path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2008.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" /> 

            …

      </httpHandlers>

</system.web>

<system.webServer>

      <handlers>

            …

      </handlers>

</system.webServer>

All you need to do to manually register the HttpHandler for the IIS7 Integrated mode is copy the Telerik HttpHandler to the <handlers> section of the <system.webServer> section group, delete the validate attribute and give it a name, e.g.:

 

<system.webServer>

      <handlers>

            …

<add name=”ChartHandler” path="ChartImage.axd" verb="*" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2008.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4"  /> 
            …

      </handlers>

</system.webServer>


Hope this helps.
