关于测量和优化网络的几乎每个方面都有丰富的文献，包括描述网页的结构和内容，设计快速加载页面的新技术，以及评估这些技术。实际上，所有这些先前的工作都使用单个页面，即着陆页（即，根文档“/”）作为该站点上所有页面的代表。在本文中，我们描述了着陆和内部（即，1000个网站的非根）页面，以证明内部页面的结构和内容与着陆页面的结构和内容以及彼此之间有很大的不同。我们回顾了2015年至2019年期间在顶级网络会议上发表的100多项研究，并强调了鉴于这些差异，近三分之二的相关研究的见解和主张需要进行修订，以适用于内部页面。展望未来，我们敦促网络社区包括内部页面，用于测量和优化网络。然而，这一建议提出了一个重要的挑战：我们如何从网站中选择一组有代表性的内部网页？为了应对这一挑战，我们开发了Hispar，这是一个每周更新的100，000页的“顶级列表”，包括约2000个网站的着陆页和内部页面。我们公开提供Hispar和重新创建或自定义它的工具。
There is a rich body of literature on measuring and optimizing nearly every aspect of the web, including characterizing the structure and content of web pages, devising new techniques to load pages quickly, and evaluating such techniques. Virtually all of this prior work used a single page, namely the landing page (i.e., root document, "/"), of each web site as the representative of all pages on that site. In this paper, we characterize the differences between landing and internal (i.e., non-root) pages of 1000 web sites to demonstrate that the structure and content of internal pages differ substantially from those of landing pages, as well as from one another. We review more than a hundred studies published at top-tier networking conferences between 2015 and 2019, and highlight how, in light of these differences, the insights and claims of nearly two-thirds of the relevant studies would need to be revised for them to apply to internal pages. Going forward, we urge the networking community to include internal pages for measuring and optimizing the web. This recommendation, however, poses a non-trivial challenge: How do we select a set of representative internal web pages from a web site? To address the challenge, we have developed Hispar, a "top list" of 100,000 pages updated weekly comprising both the landing pages and internal pages of around 2000 web sites. We make Hispar and the tools to recreate or customize it publicly available.
