Configuring FastCGI on IIS 6.0

Question

User-1910087654 posted

 First, Thank you for creating this very cool CGI capability. I have been reading all day on this subject in my attempt to convert my CGI.exe written in Basic

 So I began by using the translated headers and compiling a simple example that just echo's anything sent using POST. The compiled app is called "echo.exe"

I send it over to my server running windows server 2003 SP2 and drop it in the cgi-bin folder of my website.

I have created the website under the "Web Sites" node of IIS

and I have installed and  "Allowed" the "FastCGI Handler" under the "Web Service Extensions" node.

Now the tricky part...  configuring fcgiext.ini

In reading here:

http://learn.iis.net/page.aspx/248/configuring-fastcgi-extension-for-iis60/

I am not sure if I must create an entry for EACH of my cgi.exe executables.

Since PHP has a single executable that handles the running of ALL php scripts i suspect these settings do not apply to my situation.

Then there is the file "fcgiconfig.js"

a helper application written in JavaScript with no help for using it to configure the  fcgiext.ini file?

I assume the entire file preceeded with them so that the lines show up as comments in a code editor and are ignored, but this is not explicitly stated anywhere.

My goal is to route control based on the calling query ie

http://www.mysite.com/cgi-bin/echo.exe?txt=thisisatest

gets routed to echo.exe

http://www.mysite.com/cgi-bin/myserver.exe

gets routed to myserver.exe

How do I accomplish this?

 

Added:

The downloads section of fastcgi.com has:

 mod_fastcgi-2.4.6-AP22.dll

Which has dependant Dll's

libhttpd.dll

libapr.dll

etc

This is for Apache on windows Server?

Wade, I read your Blog

and

I too would like to create multiple FastCGI.exe that are called by name from the URL.

This does not seem to be too wild a request and I am surprised this functionality was not included in the design.

>If maintaining the external URL is important, you could write and ISAPI filter to rewrite the URLs to map nice looking external ones to the workaround above.

Could you provide a simple code example of how to do this.

How do I configure IIS 6.0  to route FastCGI requests (GET, POST on port 80) to an ip address and port that my app(running as a windows NT service) is monitoring?

e.g. localhost

"127.0.0.1" and 1027  ?

IIS fastcgi implementation only supports communication over named pipes and can only work with fastcgi processes that it launches.

Correction, tcp/ip is supported, but you cannote specify ip-address and port and IIS has to control launching of the fastcgi process.

 Anil,

Thank you for your reply.

I am confused about the purpose of the FastCGI function call:

FCGX_OpenSocket()

defined as

DLLAPI int FCGX_OpenSocket(const char *path, int backlog)

 ' * Create a FastCGI listen socket.

' * path is the Unix domain socket (named pipe for WinNT), or a colon
' * followed by a port number. e.g. "/tmp/fastcgi/mysocket", ":5000"

Can I route the incoming request to a named Pipe and specify that with this call?

 

 If Tcp/ip is supported, first, in the general case *HOW* do I configure IIS to route requests?

Perhaps I could write a FastCGI application that routes to a second application in some clever way or maybe I needto write an ISAPI filter of some kind?

No idea - this is not something that is part of IIS or the fastcgi protocol, this is a 3rd party API for writing fastcgi clients.
