Nginx, SiginalR and FastCGI with mono: No application found

Question

I'm trying to get a setup running with all these and I'm failing so hard right now. I mostly want to test Websockets, and since IIS 7.5 doesn't support them, I'm trying to set it up with Nginx and Mono/FastCGI.

So, everything is Windows based, no linux, no unix: windows. Right now, all I'm getting from calling http://localhost:7171/app (or http://127.0.0.1:7171/app) is this error:

No Application Found

Unable to find a matching application for request:

Host  localhost:7171
Port  7171
Request Path  /app/index.html
Physical Path C:\nginx\html/app/index.html

Here are the configs right now:

fastcgi.conf

fastcgi_param  PATH_INFO          "";
fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

nginx.conf

server {
listen       7171;
server_name  127.0.0.1;


#charset koi8-r;

#access_log  logs/host.access.log  main;

location / {

    #fastcgi_index index.html;
    #fastcgi_pass 127.0.0.1:9000;
    #include C:\\nginx\\conf\\fastcgi_params;
 }

location /app {

    fastcgi_index index.html;
    fastcgi_pass 127.0.0.1:9000;
    include fastcgi_params;
 }
 }

and here's the cmd line used to start fastcgi:

"C:\Program Files (x86)\Mono-2.10.8\bin\fastcgi-mono-server4" /socket=tcp:127.0.0.1:9000 /applications=/:/c://nginx//html//app

Thanks a bunch!
