During development, I usually test ASP.Net applications using the Web Development Server (sometimes called Cassini). Occasionally, when I publish to a real IIS environment, I notice that the application behaves differently.

So, what are the differences between the way that production IIS servers and the ASP.Net Web Development Server behave? I don't mean differences in feature sets (clearly IIS has lots of features that are not present in WDS), but differences in the way they handle ASP.Net.

BTW: There are a few differences noted in the responses to this question, but I am sure there must be more.
