Hi blove57,
Yes you can. By default, handlers are not allowed to be overridden in the web.config file. They are locked in the IIS 7 configuration, you need to unlock the section to allow overriding. Here is an example using appcmd.exe to unlock this section. The Command Prompt was running as Administrator.
C:\Windows\System32\inetsrv>appcmd.exe unlock config /section:system.webserver/handlers
Here is an example of web.config file with managed type as the handler.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<handlers>
<add name="WildCard" path="*" verb="*" type="sampletype" resourceType="Unspecified" />
</handlers>
</system.webServer>
</configuration>
You can also configure the handler in IIS7 Manager, please take care of the precedence of the handlers in the list in IIS7 Manager.
