Can IIS do similar to IBM HTTP Server

Hi all,



I work mainly on .NET and when we deploy 3 tier applications layers look as
below.

1. Web Server (IIS with ASP.NET (aspx) application)

2. App Server (IIS with ASP.NET Web Services (asmx))

3. Database Server (SQL or DB2 or Oracle depending on the taste of my
client)



Question #1. Am I doing something wrong?



My client asked me to convert my .NET application to J2EE (don't ask me why!
that's their organization policy).

So, I follow the same way I implemented .NET application. So, I proposed as
below:

1. Web Server (WebSphere with J2EE application (jsp) )

2. App Server (WebSphere with J2EE web services (asmx) )

3. Database Server (any)



I then discovered that IBM HTTP Server + IBM WebSphere Server do something
different. And their admin asked me to do the following:



1. Web Server (IBM HTTP Server; no installation of any application except
configuration file)

2. App Server (Web Sphere with J2EE applications and web services (both jsp
and asmx)

3. Database Server



It seems more secure to me because Web Server does not have any application
installed.



Question #2. Can IIS do similar to what IBM HTTP Server is doing?



Question #3. Can I use Web Server (IBM HTTP Server) and point to App Server
(IIS with .NET applications)



Thanks.
