Dancer::Plugin::EmptyGIF - Quick empty GIF response


 use Dancer;
 use Dancer::Plugin::EmptyGIF;
 get '/tracking/pixel.gif' => sub {
   # do something with params
   return empty_gif;



This will set your set your current request response to be an empty gif, this means, it will return binary data for the image and set the appropriate headers. You should always "return empty_gif".


An empty gif response is specially useful when you're building a webservice that processes all the URL and/or query string parameters and at the end, an empty gif needs to be returned to the client. This a tracking or reporting pixel. Once the request has reached your application code, it's better not to do any more redirections and quickly return the empty pixel from within your code.
