Figure 1: Mixed language blocks on a memento of a Twitter timeline. Highlighted with blue colored box for Portuguese, orange for English, and red for Urdu. Dotted border indicates the template present in the original HTML response while blocks with solid borders indicate lazily loaded content. Would you be surprised if I were to tell you that Twitter is a multi-lingual website, supporting 47 different international languages ? How about if I were to tell you that a usual Twitter timeline page can contain tweets in whatever languages the owner of the handle chooses to tweet, but can also show navigation bar and various sidebar blocks in many different languages simultaneously, now surprised? Well, while it makes no sense, it may actually happen in web archives when a memento of a timeline is accessed as shown in Figure 1. Spoiler alert! Cookies are to be blamed, once again .

One of the pages I came across, Hundreds of Louisiana Flood Victims Owe Their Lives to the 'Cajun Navy' , highlighted the work of the volunteer "Cajun Navy" in rescuing people from their flooded homes. The page is fairly complex, with a Flash video, YouTube video, 14 embedded tweets (one of which contained a video), and 2 embedded Instagram posts. Here's a screenshot of the original page (click for full page): Live page, screenshot generated on Sep 9, 2016 To me, the most important resources here were the tweets and their pictures, so I'll focus here on how well they were archived. First, let's look at how embedded Tweets work on the live web. According to Twitter : "An Embedded Tweet comes in two parts: a <blockquote> containing Tweet information and the JavaScript file on T
