ASP.NET versions

I have searched the forums about ASPNET / ASP.NET versions.

In Hsphere my customers can choose between 1.1.4322 or 2.0.50727.
In several posts I found out that on most of the servers ASP2.0 is upgraded to 3.5.
Does this mean that when a client chooses ASP.NET 2.0.50727 he gets ASP.NET 3.5 SP1 ?

Is 3.5 SP1 installed on all severs? Or only on all servers on cluster 2?

best regards and best wishes for 2010 to you all!

ASp.NEt 3.5sp1 is on all but Win13 on cluster1, all other servers have it. the way IIS works, 3.0/3.5/3.5sp1 are all really just extensions of 2.0, so when you assign 2.0 it is really 2.0+3.5sp1 extensions.

Thanks for the quick reply!
