I don't have time right now to make a pull requests but I put on my code, on the scraping side of it. As it's an special redirect, just in case it helps. feedproxy and feedsportal is a way to monetize feeds from Google and is very famous among occidental publishers. I hope it helps, it's written using coffeescript.
# we ensure that we're not in a feedsportal crappy ads page
if /feedsportal.com/.test(uri )
# get the correct URL from the body page
matches = /<a\s+(?:[^>]*?\s+)?href="([^"]*)"/.exec( body )
if matches
options.uri = matches[1]
parsingData.html = matches[1]
return requestArticle( options, parsingData, callback )
Example of feedproxy url: http://feedproxy.google.com/~r/libertaddigital/nacional/~3/R1fhgiVwJmQ/story01.htm
Desired url to parse: http://www.libertaddigital.com/espana/politica/2015-10-19/casado-rechaza-debate-interno-sobre-el-liderazgo-de-rajoy-pero-aznar-vuelve-a-la-carga-1276559464/
