What you're experiencing should not be anything specific to IIS6; the first
request of a IronRuby-based app is going to take a longer amount of time
because IronRuby.Rack is compiling and running all the non-app code (Camping +
other Ruby libraries, in your case). In other words, it's like your starting
the server on the first run. IIS7 defaults to 110 seconds for a timeout, and I
assume IIS6 has the same, which should be way more than enough time to start
the app; a basic Rails app takes ~15 seconds to start up on my machine. How
long does your app take to start outside of IIS? There should be no difference
whether your running in IIS or not.

Subject: [Ironruby-core] IronRuby Rack Timeout causing issues at startup
Hello,
I wanted to let you know I was having all sorts of troubles getting
Rails to start reliably running on IIS6 (though I don't think IIS6 has
anything to do with it) and I had to increase the script timeout for
the very first load of the application.
I changed HttpHandler to the one i've included below. I think the
locking is right, but has the side effect of possibly a few of the
early scripts getting a longer timeout than expected. That's probably
ok, but I'm not sure it's an "enterprise ready" solution.
What do you guys think? Source included below.
Thanks,
Martin
--------------- begin --------------------
internal sealed class HttpHandler : IHttpHandler {
private readonly Stopwatch _watch = new Stopwatch();
private static bool _isFirstRequest = true; // added this
public bool IsReusable {
get { return true; }
}
public void ProcessRequest(HttpContext context) {
lock (this) {
if (_isFirstRequest) // added this if block
{
context.Server.ScriptTimeout = 600;
_isFirstRequest = false;
}
Utils.Log("");
Utils.Log("=== Request started at " + DateTime.Now.ToString());
_watch.Reset();
_watch.Start();
Handler.IIS.Current.Handle(new Request(new
HttpRequestWrapper(context.Request)),
new Response(new
HttpResponseWrapper(context.Response)));
_watch.Stop();
Utils.Log(">>> Request finished (" +
_watch.ElapsedMilliseconds.ToString() + "ms)");
}
}
}
