ASP Sessions and Web Gardens

[Andrew Durstewitz]

I'm working with a Windows 2003 IIS 6.0 Server with 2 2.8Ghz HT
processors (4 Proc to the server because of the HT).

My problem I that I have web garden turned on and can't get the sessions
to stay. I am new to IIS 6.0 so I don't know much about the whole web
garden thing. However, my entire site is written around ASP using
Sessions.

Any ideas on how to make this run on the new server?

Thanks,
Andrew J Durstewitz

You can't enable web-gardens and use instrinsic ASP Sessions.

When you enable a web-garden, you are allowing IIS to create multiple
w3wp.exe to service that application pool. Each w3wp.exe process has it's
own memory, threads etc. They certainly don't know about ASP sessions
created in other processes.

For a Classic ASP app, you'd need to roll your own session state mechanism
that worked with some other kind of storage (outside the w3wp.exe
processes).

For an ASP.Net application however, it's very east to switch between the
intrinsic session state systems (inproc, session state service, and SQL
Server). With an ASP.Net application, you shouldn't use inproc session state
with a web garden, but you can switch to either of the other two systems.
With the other two systems, session state is stored externally, so no matter
which w3wp.exe process answers the incoming request, the process can
recreate the session state from the external session store.

You can have multiple processes serving a single web application pool.

On IIS v5, this required mulitple physical processsors, but in IIS6 it no
longer requires that. If one process, for whatever reason, is busy, it means
that another process is still available to service incoming requests.

Check the IIS6 Resource Kit for more information:

: Hi
:
: Just picked up on this and I know it will probably sound a very dum
: question, but what pratical uses would a web garden bring to a developer?
