Hi all, I’ve got a Windows 2008 / IIS 7 server, and a default Rails app working with: Rails 2.3.5 Rack gem (1.0.1) IronRuby 1.0 RTM IronRuby.Rack.dll built from Git HEAD. It seems like images are being corrupted? Static content like /javascripts/prototype.js looks fine, but I get a broken image when requesting /images/rails.png Running curl, the headers looked OK: HTTP/1.1 200 OK Cache-Control: private Content-Length: 6646 Content-Type: image/png; charset=utf-8 Last-Modified: Thu, 20 May 2010 18:50:34 GMT Server: Microsoft-IIS/7.0 X-AspNet-Version: 4.0.30319 X-Powered-By: [ASP.NET](http://ASP.NET) Date: Fri, 21 May 2010 18:11:54 GMT (However, it displays correctly when using the local “ir script\server” (just webrick) [http://localhost:3000/images/rails.png](http://localhost:3000/images/rails.png)) (It looks like Bobby J. has the same or similar issue in his screencast @ [http://www.iamnotmyself.com/2010/04/22/RunningRailsInIIS7WithIronRubyRack.aspx](http://www.iamnotmyself.com/2010/04/22/RunningRailsInIIS7WithIronRubyRack.aspx)(15m 04s)) Any ideas? Thanks, Ed C. ---

Hi Eddie, This is a known issue with the ironrack implementation. I had thought it was going to be fixed with the next push to github, but it looks like it was not. try searching the mailing list for jimmy’s comments on it. couple workarounds for you… 1. fix it… 8) 2. set up a images subdomain for hosting image files that does not go though rack. so all your images would come from [images.mysite.com](http://images.mysite.com).

Hi Bobby, I hadn’t seen anything on the Codeplex site, but I did just find this post from Jimmy @ [Attempting To Get IronRuby.Rack Running a non-demo rails site - IronRuby - Ruby-Forum](http://www.ruby-forum.com/topic/208064#905769) (Apologies for beating a dead horse.) We’ll be using static asset hosts in production, so using them in development for the short term works too. Thanks! ---

Yep, this is a known bug in the current sources; we used response.Write instead of response.WriteBinary. If you change Hosts/IronRuby.Rack/Response.cs to use that, images and other binary files will work again. Also, it’s another bug that the adapter is serving static files through Rack, it should just find them itself. This bug and the image bug will be checked in this weekend. Let me know if you have any issues. ~Jimmy On May 21, 2010, at 2:33 PM, “Eddie Cianci” \ wrote: Hi all, I’ve got a Windows 2008 / IIS 7 server, and a default Rails app working with: Rails 2.3.5 Rack gem (1.0.1) IronRuby 1.0 RTM IronRuby.Rack.dll built from Git HEAD.
