Hi,

Doesn't matter if is CGI or FastCGI. Same problem.

I did more tests.
In my example, I have 1 Module "pdf" and 1 Action "act1".

The Module has a DataModuleRequest event:
begin
  AResponse.Content := 'default';
  Handled := True;
end;

The Action has a Request event:
begin
  AResponse.Content := 'list';
  Handled := True;
end;

#1 Call Action
URL: http://localhost:2015/fcgitest.exe/act1/
Result: error - Could not determine HTTP module for request "act1"
Log:
PATHINFO=/fcgitest.exe/act1/
NEXT_PATHINFO=fcgitest.exe

#2 Call Module/Action
URL: http://localhost:2015/fcgitest.exe/pdf/act1/
Result: print - "default"
Log:
PATHINFO=/fcgitest.exe/pdf/act1/
NEXT_PATHINFO=fcgitest.exe

If you do not have time, maybe I can try to fix. But how we
can know what Server is running (Apache, IIS, etc)?

Thanks,
