Either you just create multiple instance scripts, each for one sub- application or you can do it with one instance script if you use CGI::Application::Dispatch. The overall structure is the same in both cases. You usually have a base class with all the common stuff in it, like loading plugins, setting up the templating system, taking care of authentication, session stuff and so on. Then I have several sub-applications, all inheriting from the base class, say one for customers, one for products. The customer class would have runmodes like add_customer, edit_customer, show customers and perhaps something like a special runmode "all my very best customers I want to invite to the football world championship final Germany-Brasil" ;-) Each runmode usually comes in a display and a process variant. The different sub-applications are connected through links. E.g. I could have some links on one of the customer pages to all the products the customer bought in the past. Such a like might look like "/cgi-bin/products.pl?rm=show_product&id=5" or '/business/product/5' if you use CA::Dispatch and perhaps a little bit of mod_rewrite. The only difficulty is, if you want a cross-sub-application connection not by a link but through a form submission. That was my problem the other day. I really don't know if this kind of layout will lead to major problems or is somewhat proven and recommended. My current project is the first of such a size that I didn't want everything in one class and in one file, it just looked very messy, so I tried to tidy it up a bit.
