Re: CGIDEV Question -- WEB400

Thanks Matt. Good tips.  One question.  Where does the output from ending
the http server go when you end the server after starting it with -vv? Is it
a spooled file owned by QTMHHTTP or is it dumped to the HTTP server log? 

I've looked all around and cannot locate it after starting it and ending the
server using -vv.

Thanks,

You should enable the error log and see what's in it. Here's some
configuration directives that will turn on access and error logging and
keep the logs for two weeks:

LogFormat "%h %{Host}i %u %t \"%r\" %>s %b \"%{Referer}i\"
\"%{User-agent}i\"" combined
CustomLog logs/accesslog combined
ErrorLog logs/errorlog
LogMaint logs/accesslog 14 0
LogMaint logs/errorlog 14 0

If I'm not mistaken, header errors will show up in the error log. Also,
if you start the server with -vv (two lower case V's), run the request,
and end the server, it will do what essentially amounts to a comm trace
and you'll be able to see exactly what it s passed in and what is
returned.

Additionally, this is most likely a problem with the content-type header
(configuration errors typically show up as a 404 or 403 error). As has
already been pointed out, the Original HTTP server would automatically
set one if a CGI program didn't set it or mangled it badly. Apache
doesn't do that but I think you can add a MIME type to it for .pgm
objects (if you have CGI programs that generate something other than
HTML, you'll want to check them after making this change).

I'll do better than that. I'll post the whole config. All of this also
has
to be SSL enabled so I went ahead and put that back in too in the config
file.

I can bring up the main index page with just the domain name in the
address
bar, no problem.        http://mydomain.com

And I can also bring up the main index page in the address bar using
https://mydomain.com. 

Also, I can open my own CGI program (one I wrote to see if the CGI
directives were set up correctly or not) and I can access it securely
using 

https://mydomain.com/cgi-bin/mycgiapp


However, when I attempt to open one of the existing CGIDEV2 programs the
browser does not know what to do with it and instead prompts me to save
it
to my hard drive.

This leads me to believe that the CGI directives probably are correct,
but
that the content-type value is missing from the CGIDEV2 program.  But
I've
been wrong before...

Thanks for looking at this.

Post the scriptalias directive.  Maybe it's set up so you
don't need the .pgm at the end of the program name.

But, if you can't even telnet to port 80, I'd question if
the HTTP server is running or set up properly.
