Hi,

I have written a patch to the FastCGI ISAPI DLL that emulates the autoUpdate feature of the FastCGI module for Apache. With this feature, the FastCGI process manager checks with each request if the dynamic server's program has changed on disk since the dynamic server process was started. If it has, it shuts down any currently running dynamic server processes and starts new ones. This is a very handy feature especially with systems under development.

Note that this need arises not from PHP usage but from using the FastCGI ISAPI DLL to run Perl programs as FastCGI applications. I previously opened a related bug (#37238) which was very kindly addressed by edink.

I have posted my patch here:

Using the new feature is a matter of adding this DWORD to the Registry and setting it to 1:

HKLM/SOFTWARE/FASTCGI/DynamicAutoUpdate 

By default, this feature is turned off.

For reference, the FastCGI Apache module autoUpdate feature is described here:

And it's implementation may be seen here (search for "// It exists"):

Thanks,
