What I'm hoping to discover is a solution to turn of the caching on the development machine, so that I can quickly make changes without having to restart or "refresh constantly" to un-cache an error.
Um, if you don't want a persistent process, with all the benefits it brings, run it as CGI :/
OTOH, how tightly is your module/app coupled with Apache? you can always develop with plackup/Plack::Middleware::Refresh / Plack::Loader::Shotgun for faster reloading :)
What he is saying seems true and is the case when I'm most frustrated.
Sorry , but it isn't. He said if you change the Perl code, you must restart Apache. which is obviously false (hello Apache2::Reload) because like Apache2::Reload like reloads stuff
