TFastCgi Class Reference

THttpEngine implementation, based on fastcgi package.

Allows to redirect http requests from normal web server like Apache2 or lighttpd

Configuration example for lighttpd:

server.modules += ( "mod_fastcgi" )
fastcgi.server = (
   "/remote_scripts/" =>
     (( "host" => "192.168.1.11",
        "port" => 9000,
        "check-local" => "disable",
        "docroot" => "/"
     ))
)

When creating THttpServer, one should specify:

THttpServer* serv = new THttpServer("fastcgi:9000");

In this case, requests to lighttpd server will be redirected to ROOT session. Like: http://lighttpdhost/remote_scripts/root.cgi/

Following additional options can be specified

top=foldername - name of top folder, seen in the browser
thrds=N        - run N worker threads to process requests, default 10
debug=1        - run fastcgi server in debug mode

Example:

serv->CreateEngine("fastcgi:9000?top=fastcgiserver");
