Thread: web.config <handlers>

I presume you mean the <handlers> section under <web.server>?

What happens when you leave the <handlers> section in? Do you get any error messages?

Could you post the <handlers> section that you remove?

Here is the handler section from teh web config

Code:

<handlers>
<remove name="WebServiceHandlerFactory-Integrated" />
<remove name="ScriptHandlerFactory" />
<remove name="ScriptHandlerFactoryAppServices" />
<remove name="ScriptResource" />
<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add name="ScriptResource" verb="GET,HEAD" path="ScriptResource.axd" preCondition="integratedMode" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</handlers>

I am trying to sort out what error it is as it is just a blank screen at the moment, but I think it is a 500 internal error reply. I am new to all this as I am just moving from classic asp to .net so I will apologise if I sound thick.

The handlers section looks identical to the one I use.

Check you have .NET Framework 3.5 SP1 installed on the server.

Also try checking in the Handler Mappings in IIS to see if you have the following entries:-

Code:

PageHandlerFactory-Integrated | *.aspx | Enabled | Unspecified | System.Web.UI.PageHandlerFactory | Local
PageHandlerFactory-ISAPI-2.0 | *.aspx | Enabled | Unspecified | IsapiModule

WebServiceHandlerFactory-Integrated  | *.asmx | Enabled | Unspecified | System.Web.Services.Protocols.WebServiceHandlerFactory, System.Web.Services, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
WebServiceHandlerFactory-ISAPI-2.0 | *.asmx | Enabled | Unspecified | IsapiModule

There may also be one for .axd files as well
I think I had to alter something in the Handler Mapping with 3.5.

Hope that helps.

Is there anything in the eventlog to suggest what the error might be?

You could also try having a look at this article. Specifically the bit about the application pool setting.

Have a look in

Code:

Server Manager -> Diagnostics -> Event Viewer -> Custom Views -> Server Roles -> Web Server

And

Code:

Server Manager -> Diagnostics -> Event Viewer -> Custom Views -> Administrative Events

If you double click on the event it'll give a full description of the problem.

Here is the log, but it means nothing to me, maybe it does to you.

A friend has just sent this http://technet.microsoft.com/en-us/l.../cc627314.aspx but it is totally over my head.

Thanks

Can you please post your entire web.config? Also, are you by any chance using AJAX on the EditNews.aspx page?
