[Dancer-users] ajax plugin strangeness

12 Oct 2011

      Perhaps I don't understand how to correctly use the Dancer::Plugin::Ajax. I am running Dancer 1.3072 with Dancer::Plugin::Ajax running off of Starman proxies behind Apache2. I experience the following strangeness (which, you can test at http://humanesettlements.punkish.org)... Some Ajax queries (sent via jQuery) return as JSON, while others return as full html in spite of having identical headers. My server side code is

	ajax '/' => sub {
		my $page = params->{'page'} || 1;
		my $tags = params->{'tags'};

		my $res = query('page' => $page, 'tags' => $tags);

		return to_json \%res;
	};

	get '/' => sub {
		my $page = params->{'page'} || 1;
		my $tags = params->{'tags'};

		my $res = query('page' => $page, 'tags' => $tags);
		template "ideas", \%res;
	};

Here are the queries as captured in the web debugger (in Safari). The following returned JSON

	• Request URL:http://humanesettlements.punkish.org/?tags=old_people
	• Request Method:GET
	• Status Code: 200 OK
	• Request Headers
		• Accept:application/json, text/javascript, */*; q=0.01

The following failed in that it returned full HTML content in spite of sending the correct revue headers
