Description:
------------
(I apologize if I am reporting this in the wrong place. It seems that Shane Caraveo's fastcgi-isapi module is now being maintained as part of the PHP project. This is a great DLL for general FastCGI applications and not just PHP. The problem I found relates to using it with Perl to run dynamic servers. As such, it's not terribly relevant to your work but I thought I'd report it along with patches.)

1. When using the fastcgi-isapi DLL to run dynamic servers, the dynamic servers are running as FastCGI filters rather than responders. This is due to a structure's member not being initialized.

2. When using perl as the server executable, it is sometimes necessary to include arguments like -T and -w. The Args value in the registry is being ignored for dynamic servers.

Here are the patches I applied to the code in CVS to fix these problems:

                proc->env.putEnv("_FCGI_NTAUTH_IMPERSONATE_=1");

And I also needed this change to compile it on my machine:

Given these changes and registry settings like the following, I was able to successfully run perl dynamic servers with the fastcgi-isapi module:

HKEY_LOCAL_MACHINE\SOFTWARE\FASTCGI\.pl

In this key, I added the following values:

AppPath REG_SZ c:\tools\perl\5.6.1\bin\MSWin32-x86\perl.exe
Args REG_SZ -T
BindPath REG_SZ

Note that the value of Args is "-T " (with a space). BindPath is empty. (Perhaps it's not necessary.)
