Has anyone tried using Rails (or PHP or whatever) on IIS lately? There  
is a FastCGI extention for IIS 5.1 and 6.0 [1], backported from IIS7 if  
I understand correctly. I’m curious if anyone thinks this would work in  
production and give Rails a decent inroad for IIS-based shops. It seems  
to perform [2] but I would like some verification from the community at  
large before I mention the “R” word at work again. 🙂

I’ve done tons of work with Rails on IIS. The bottom line is that it’s  
not  
worth it right now, as FastCGI is not a good, scalable way of deploying  
Rails. It works ok for a single application, but things start to get  
messy  
with multiple apps

The best aproach is to deploy Mongrel on the Windows machine and then  
use  
Apache + mod\_proxy\_balancer. I’ve posted lots of stuff on this before.  
Various setups for Windows-based deployments are also outlined in the  
next  
beta release of Deploying Rails Applications. (  
[Pragmatic Bookshelf: By Developers, For Developers](http://www.pragprog.com/titles/fr_deploy)). In that book, I explain how  
to  
graft Rails apps onto an existing IIS server so you can share  
certificates  
or even move the apps to a Linux box or other machines so you can  
actually  
scale upwards.

If you want to talk specifics, don’t hesitated to contact me off-list.  
I’d  
be glad to share information with you.
