Re: [cgiapp] Determining Content type in postrun (Re-send)

["Rob Kinyon" <suppressed>]

Rhesa already answered your immediate question. I'm going to give you
some advice in terms of why what you're doing isn't the best.

In general, headers and footers should be managed by the templating
system you're using. For example, I use Template Toolkit (TT) and it
has the [% INCLUDE %] directive. HTML::Template has <TMPL_INCLUDE> and
the others have similar directives.

So, why should you do this? It all boils down to MVC - Model vs. View
vs. Controller. Read
http://en.wikipedia.org/wiki/Model-view-controller then come back to
the following.

The content you present to the user should be managed by your view,
not your controller. In this case,your CGI::Application subclass is
your controller and TT (or H::T, Mason, Embperl, etc) is your view.
(Your model would be your database, in most cases, plus whatever
business objects you have.) In the cases where you have headers, your
template should be doing the right thing. In the cases where you
don't, your template should still be doing the right thing. Your
controller doesn't want to care about headers and such. It's too much
work for it.
