I'm running a ServiceStack application on IIS. My regular services work fine and have not had any problems with permissions.

My new project involves providing generated pdfs. I gave IIS_IUSRS read/write permissions to the Temp directory under my app directory. I also allow non SSL connections to this directory. When I browse to the file which ServiceStack is supposed to automatically serve up (eg. http://ryu.com/Temp/201310171723337631.pdf ) I get this:

Forbidden


Request.HttpMethod: GET
Request.PathInfo: 
Request.QueryString: 
Request.RawUrl: /ryu/Temp/201310171723337631.pdf
App.IsIntegratedPipeline: True
App.WebHostPhysicalPath: C:\inetpub\ryu
App.WebHostRootFileNames: [global.asax,global.asax.cs,web.config,bin,temp]

Now this doesn't look like a ServiceStack error message, more like IIS, but I'm not certain as to how to get to the bottom of this. Authorization settings are Allow All.
