I didn't get too far with IIS7 and Vista at home, but at work I've got Win2K3 and so IIS6. I installed FastCGI TP2 and got it talking to RoR in half a day. I'm also talking to an MS SQL database. All is good.
I do have what looks like a session timeout problem. After a few minutes ruby shuts down so the next request takes a while to get going. I think I may not have set my ini file up correctly:
ExePath=D:\Applications\Ruby\bin\ruby.exe
Arguments=D:\Data\Rails\myApp\public\dispatch.fcgi
IgnoreDirectories=0
IgnoreExistingFiles=1
QueueLength=1000
MaxInstances=4
InstanceTimeout=1200
ActivityTimeout=3000
InstanceMaxRequests=200
It could be the InstanceTimeout, but I haven't found any way of setting this to infinite, which would be ideal for me - I guess I've set it to 20 mins. However another opst indicates this parameter is deprecated.
It's not a major for me. I'm just happy that I can do Rails under IIS. At home, I'm plodding on with Rails under apache.
