var source = webClient.DownloadString(url);

When importing a video inside the media library, if the video is from Vimeo, the download fails with a http 429 status (too many requests). This seems an issue related to the fact Vimeo forbids the scraping of its pages (which Youtube still consents), making it impossible to import its videos inside the media library.
