That is exactly what the RewriteRule is doing...

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

In english, it is saying, "if the path in the browser looks like a
'slash' followed by 'App1' possibly followed by other text (note,
there is no 'dispatch.cgi' in the path in the browser', take all of
the other text and stick it in '$1', then pretend the following path
was requested - a 'slash' followed by 'App1/public/dispatch.cgi'
followed by everything that was stuffed away in '$1'". So, I request
'/App1/icovnik', and the server processes the command
'/App1/public/dispatch.cgi/icovnik' which is taken by Dancer and
broken into params->{:p} that you can now use in your query.
