[fix] google news - send CONSENT Cookie to not be redirected In the EU there exists a "General Data Protection Regulation" [1] aka GDPR (BTW: very user friendly!) which requires consent to tracking. To get the consent from the user, google-news requests are redirected to confirm and get a CONSENT Cookie from https://consent.google.de/s?continue=... This patch adds a CONSENT Cookie to the google-news request to avoid redirection. The behavior of the CONTENTS cookies over all google engines seems similar but the pattern is not yet fully clear to me, here are some random samples from my analysis .. Using common google search from different domains:: google.com: CONSENT=YES+cb.{{date}}-14-p0.de+FX+816 google.de: CONSENT=YES+cb.{{date}}-14-p0.de+FX+333 google.fr: CONSENT=YES+srp.gws-{{date}}-0-RC2.fr+FX+826 When searching about videos (google-videos):: google.es: CONSENT=YES+srp.gws-{{date}}-0-RC2.es+FX+076 google.de: CONSENT=YES+srp.gws-{{date}}-0-RC2.de+FX+171 Google news has only one domain for all languages:: news.google.com: CONSENT=YES+cb.{{date}}-14-p0.de+FX+816 Using google-scholar search from different domains:: scholar.google.de: CONSENT=YES+cb.{{date}}-14-p0.de+FX+333 scholar.google.fr: does not use such a cookie / did not ask the user scholar.google.es: does not use such a cookie / did not ask the user Interim summary: Pattern is unclear and I won't apply the CONSENT cookie to all google engines. More experience is need before we generalize the CONSENT cookies over all google engines.
