<p>That's a good question. We actually tried to make it the default
a while back, but unfortunately a lot of apps are not compatible
with this setting. Particularly WCF apps had problems with this
configuration. That's the reason we reverted the change and added
it to the KB article instead.</p>
<p>Introducing new defaults is almost always a bit tricky
considering the volume and diversity of the apps deployed to
AppHarbor. We're considering various other approaches to alleviate
the issues related to running an IIS app in a load balanced setup,
and more generally, presenting recommended configurations that can
optionally be selected when creating the app.</p>
<p>Best,<br>
