To set this up at the machine level, add the following line to the <httpHandlers>
section of %windir%\Microsoft.NET\Framework\v1.1.4322\CONFIG\machine.config:
<add verb="*" path="precompile.axd" type="System.Web.Handlers.BatchHandler"/>
To set this up at the application level, add the you'll need to create an httpHandlers
section like so: [JonGalloway]
<configuration>
<system.web>
<httpHandlers>
<add verb="*" path="precompile.axd" type="System.Web.Handlers.BatchHandler"/>
</httpHandlers>
</system.web>
</configuration>
