in reply to Struggling to understand making CGI::Application RESTFUL

I can't help with the dispatch stuff, except to snipe that Catalyst::Controller::REST might make it easy. :) As far as the REST design goes. Try to keep verbs and ranges out of URIs. I'd expect /products by itself to return "all" products or at least take a query arg to do so. PUT *is* add. So- 

GET http://example.com/products/all
# becomes
GET http://example.com/products
# or maybe something like
GET http://example.com/products?rows=all
# or
GET http://example.com/products?from=1;to=-1

# And then
PUT /etc/passwd http://example.com/products/add
# becomes
PUT /etc/passwd http://example.com/products
# or maybe better
PUT /etc/passwd http://example.com/product

Unless things have progressed recently, you'll also have to "overload" POST to do the "PUT" work since PUT isn't universally supported.

    Well ... PUT has been supported by CGI (and hence CGI::Application) since version 3.31 -- I know, it was the fine monks here that helped me create the patch! (REST Webservices and CGI.pm). There's probably a CGI::Application plugin to make it really easy but here's how I've been doing rest services with CGI::Application: 

    sub setup {
  my $self = shift;
  my $cgi  = $self->query();

  $self->start_mode( $cgi->request_method() );

  $self->run_modes(
    'PUT'       => 'update',
    'GET'       => 'retrieve',
    'POST'      => 'create',
    'DELETE'    => 'delete',
  );
}

      The issue is client-side support and the HTML spec. Some browsers do the right thing now but it's not because they are supposed to as much as they are trying to bridge the gap.

    since PUT isn't universally supported

    PUT has been part of HTTP since 1997 .... oh right, nothing is universally supported, like html4 forms don't support PUT, but html5 forms do ...
