Web.config ships this:
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="2048000000" />
<denyUrlSequences>
<add sequence=".php" />
</denyUrlSequences>
</requestFiltering>
</security>
Is there any special concern we should be aware of when removing this because we want to able to have 301 redirect-maps that has .php URLs?
