FYI, tracking issue here:
http://github.com/jschementi/ironruby/issues/#issue/24
(I'm playing around with GitHub's issue tracking for current Silverlight and
Rack work at the moment --- if any of these bugs are "keepers" they'll be moved
to codeplex)
A fix will be in shortly, but that whole section needs some TLC.

Subject: [Ironruby-core] IronRuby Rack handling of POST-ed data
As I continued get my Camping app to work in IronRuby Rack, I noticed that I
kept getting the following error when a form was POST-ed to the server:
[InvalidOperationException: can't convert System::String into String]
Microsoft.Scripting.Interpreter.ThrowInstruction.Run(InterpretedFrame frame)
+58
Microsoft.Scripting.Interpreter.Interpreter.RunInstructions(InterpretedFrame
frame) +90
Microsoft.Scripting.Interpreter.Interpreter.Run(InterpretedFrame frame) +278
Microsoft.Scripting.Interpreter.LightLambda.Run2(T0 arg0, T1 arg1) +341
IronRuby.Runtime.RubyScriptCode.Run(Scope scope, Boolean bindGlobals) +293
IronRuby.Runtime.RubyScriptCode.Run(Scope scope) +39
Microsoft.Scripting.SourceUnit.Execute(Scope scope, ErrorSink errorSink) +138
Microsoft.Scripting.SourceUnit.Execute(Scope scope) +43
Microsoft.Scripting.Hosting.ScriptSource.Execute(ScriptScope scope) +75
IronCamping.RubyEngine.Execute(String code, ScriptScope aScope) in
E:\DEV\POC\IronCamping\IronCamping\RubyEngine.cs:56
IronCamping.IIS.Handle(Request request, Response response) in
E:\DEV\POC\IronCamping\IronCamping\IIS.cs:177
IronCamping.HttpHandler.ProcessRequest(HttpContext context) in
E:\DEV\POC\IronCamping\IronCamping\HttpHandler.cs:41
System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
+181
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&
completedSynchronously) +75
As a work-around I found that if I explictly passed the request.Body as a
string using the following code to set the rack.input environment variable in
the Handle mthod of IIS class, the issue went away:
if (request.Body != null)
{
// Explicitly pass the request body as a string
string myInput = request.Body.ToString();
handle_scope.SetVariable("__myinput", myInput);
env["rack.input"] = RubyEngine.Execute("StringIO.new(__myinput.to_s)",
handle_scope);
}
else
{
// Original code
env["rack.input"] = RubyEngine.Execute("StringIO.new(__request.body ||
'')", handle_scope);
}
(Original code in GitHub:
http://github.com/ironruby/ironruby/blob/adb33b18780e5f2a7e050fd38ebc58750ec1cf5b/Merlin/Main/Hosts/IronRuby.Rack/IIS.cs)
Is this the right way to go?
