This is really a webserver configuration issue, but just I wanted to
reaffirm that it's very possible under Apache or most other webservers.
For our application I'm running mini_httpd, which is not super high
performance, but seems to be the smallest and simplest webserver that
will do SSL. For this webserver, the CGI mapping is simply a list of
shell glob patterns that you set in the configuration file.
For Apache, the configuration is done via the ScriptAlias directive.
The standard convention is to map "/cgi-bin/" in the URL's path, like
this:
ScriptAlias /cgi-bin/ "/usr/local/apache/share/cgi-bin/"
But you can just as easily map some other path, for instance:
ScriptAlias /gui/ "/usr/local/mycoolguiscripts/"
or (I think)
ScriptAlias /gui/ "/usr/local/cgi-bin/thisdoesitall.pl"
If you want to have one script for everything, you can, as you noted,
take its invocation info out of PATH_INFO with something like this near
the head of your script:
my $name = $ENV{PATH_INFO};
$name =~ s%^.*/gui[^/]*/%%;
# Add trailing index.html if filled in by web server
$name =~ s%/$%/index.html%;
# Remove leading slash
$name =~ s%^/%%;
Then access to "http://www.example.com/gui/home.html"; would result in
$name being set to "home.html", ready for concatenation of your
template path prefix.
If you have a number of different scripts for different elements of
the user interface, one strategy is to hard- or soft- link those
scripts into all the appropriate points in the URL hierachy where
ScriptAlias points, and then you can simply use SCRIPT_NAME as the
starting point instead of PATH_INFO.
