Hi,
I'm trying to set up a simple app, but unfortunately, it should run as
old CGI script under Apache on Linux.
The CGI script is reachable via http://server/appdir/script.cgi. I
have set appdir/.htaccess like this:
RewriteEngine On
RewriteRule ^(.*)$ script.cgi
The RewriteRule should be probably something like this:
RewriteRule ^(.*)$ script.cgi?$1
Not really, the rewrite rule should not path the path_info as a
QUERY_STRING.
...
[...]
Please assume that I am unable to run the application under FCGI or
mod_perl. The Dancer's http server works but I need to make it work on
our server... so... as plain CGI.
What you want to deploy is supported by Dancer with Plack, that works,
and I'm going to give you a working example (which will then be added to
Dancer::Deployment).

This is how I deploy my test applications:

I have a Virtualhost that matches *:80 which provides a bucnh of Dancer
apps served within their own directories. This way I can access "AppFoo"
with http://localhost/AppFoo/ (If understand you well, this is what you
want).

The following example provides /App1/ served by CGI and /App2/ served by
FastCGI.

Here is all that you need to get this working:

<VirtualHost *:80>
        ServerName localhost

        # This is the root directory of all the apps
        DocumentRoot "/PATH/TO/YOUR/ROOTDIR"  

        RewriteEngine On
        RewriteCond %{REQUEST_FILENAME} !-f

        <Directory "/PATH/TO/YOUR/ROOTDIR">
                AllowOverride None
                Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
                Order allow,deny
                Allow from all
                AddHandler cgi-script .cgi
                AddHandler fastcgi-script .fcgi
        </Directory>

        RewriteRule /App1(.*)$ /App1/public/dispatch.cgi$1 [QSA,L]
        RewriteRule /App2(.*)$ /App2/public/dispatch.fcgi$1 [QSA,L]
</VirtualHost>

Please note that the RewriteRule does not use a question mark, the
rewritten path should look (internally) like the following:

/App1/foo/bar => /App1/public/dispatch.cgi/foo/bar

request->path will then be - as you can expect - "/foo/bar"

This works perfectly well on my box, it should work on yours ;)

Good luck.
