I'm learning rails in a microsoft shop, where asking for an apache
install will be controversial. The bits I've been reading about how to
install a rails app on IIS are fairly daunting, and I have this nagging
feeling that it should be possible to crib something together w/ms'
HTTPHandler stuff in asp.net. Probably this is just foolish, but can
anybody recommend reading that would lay out some of the issues involved
in having a rails server like mongrel talk to a web server?
Thanks!

Well, I have no idea how to do this, but you need to start by
researching how to use IIS as a proxy server. Here's the concept of
what happens when you use an Apahce/mongrel combo with 2 mongrel
instances (called a "mongrel_cluster").
It doesn't work exactly like a round-robin -- that's just for
demonstration -- it uses mod_proxy_balancer to balance the requests
between all the mongrel instances. You can operate a small website
off of one mongrel, but if you get 2 requests within the same quarter-
second (or however long it takes mongrel to execute the first request)
the second request will have to wait until the first finishes.
Also, remember that Apache runs on Windows, too -- you'll probably
have to compile the appropriate modules, though.
Now for what you know your going to hear: I really don't recommend
this. A good Engineer (i.e. a good Software Engineer) chooses the
right tool for the job. If the job requires Linux and Apache, that's
what you ought to use. Likewise, if the job requires IIS, that's what
you ought to use. Also, remember that the "right" tool is the one
that is most efficient (both coding efficiency and running-
efficiency), most secure, etc. Politics really isn't a good measure
of "rightness," as a matter of fact, politics has a tendency to work
against rightness.
Thanks very much--I may try and look into this. I guess the (somewhat)
tricky bit is to rejigger the URLs in the outgoing HTML stream so that
they no longer refer to particular Mongrel instances (ports & so on) but
rather to the IIS "application". Ooh--and to convey cookies, request
parameters, user agent strings, etc. from end users to the mongrels...
Feh, that's starting to sound like work.
And totally well-taken on the 'right tool' stuff. I consider my effort
an attempt to expand the toolbox here, but I am definitely sympathetic
to our IT folks' desire to not have lots of webservers to admin. I
would really like to be able to tell them a lovely story about how rails
can fit into our existing infrastructure w/out too much fuss or
bother...
Well, that's promising. Can you say what docs you used to guide your
setup? Thanks!
Yeah, the cost of isapi_rewrite was a definite turn-off--kind of kills
the FOSS buzz behind using ruby and rails (not that IIS doesn't but at
least that's already bought).
Thanks!

I tried the stealth approach first: fired up a Linux server in VMWare
on the IIS server. Once it proved it's worth, it was not hard to get
buy in for the server to be a full time player in the domain.
IIRF (http://cheeso.members.winisp.net/IIRF.aspx ) is an open-source

There is someone else who used IIRF in a RoR scenario, look for
