Jaime,
I thought of a way to do this a while back...
First off, you could make mini_httpd (and Linux) treat .cfg files as
CGI and call something in PHP, etc to generate them on the fly. Now
you only have one problem - mini_httpd will still return an HTTP 404
for any files that don't exist. Hmm... A while back I had a patch to
mini_httpd that would look at the User-Agent header and use a custom
polycom error document if the client was a Polycom. The only trick
was getting the CGI code ini mini_httpd to actually *execute* for
error pages. I got stopped there.
You could make your Grandstreams use HTTP and modify this code a
little for their user agent string, file format, etc.
This is the kind of thing that would be pretty straight forward in
Apache. But that's not fun, is it? :)
I've attached the small patch to these e-mail to hopefully get you started.
