iis 7 server configuration

Oct 16, 2008 at 12:57 PM
Hi.  We have already installed a small demo project on a remote server running iis6 which works correctly.  We have installed a trial copy of Windows Server 2008 with iis7 and the demo no longer functions.  The operation crashes when updating the PartialUpdatePanel with an error 'Resource cannot be found'.  'http:404' requested url /partialupdatepanelloader.ashx'

it would appear that it is a server configuraration error. Can anybody have any experience of iis7  configuration or the partialupdatepanel help us with this problem.

We are running .net 3.5 with sp1

Thank you

I havn't much experience with IIS 7 yet, because we are still running Windows Server 2003.
But I think a solution my be the following:

Using IIS 7 you have to configure the <system.webServer> section in your web.config.
This section makes most of the settings in <system.web> obsolete.

So try to add the handler in <system.webServer>:

        <add verb="*" path="PartialUpdatePanelLoader.ashx" validate="false" type="iucon.web.Controls.PartialUpdatePanelHandler"/>

Please let me know if this works.

You shuld use this code in your web.config

    <validation validateIntegratedModeConfiguration="false"/>
 </modules> <handlers> [...]
<add name="PartialUpdatePanelHandlerHandler" verb="*" path="PartialUpdatePanelLoader.ashx" type="iucon.web.Controls.PartialUpdatePanelHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode" /> </handlers> </system.webServer>
Thanks Stefan for your great job!
