[Dancer-users] Where do I get POST form data in a post route?

[Leandro Hermida]

Hi,

Just want to say thanks for the email replies to help, it was actually
really straightforward to take existing CGI.pm scripts and migrate them to
the Dancer framework, for the first major step simply copying the CGI code
as is into Dancer routes and changing obvious things like:

- print $html --> return $html
- $cgi->params --> params
- print $cgi->redirect(...) --> redirect '...'
- print $cgi->header(...) --> headers '...'

After these small changes everything works just like it did before and you
can use the web app as is.  As a next step I have to start using the
templating and layout functionality and all the other nice features.

thanks again,
Leandro
