ネット上のプライバシーを強化する Oblivious HTTP
インターネットユーザーの間では、自分たちの個人情報は誰に収集されているのか、そしてそのような情報を利用して、自分のオンライン (もしくは現実の世界) での活動の様子が他者に見えてしまうのではないかという懸念が高まっています。同時に、ほとんどの人が便利で実用的なWebサイトやモバイルアプリがもたらす恩恵を受けており、プライバシーの保護を理由にそれらすべてを諦め、インターネットとのつながりを断って今の社会で暮らすことは簡単ではありません。 インターネットサービスを提供する企業は、サービスの有用性とプライバシーの確保という競合する優先事項の間で、どのようにバランスを取るべきかという点において厳しい選択を迫られています。企業は、通常のサービスの運用を通じてエンドユーザーに関するデータを受信するだけでも、厳しいコンプライアンス要件と規制当局からの圧力に晒されます。サービスが成功を収めるほどに、これら
Beyond Server Push: The 103 Early Hints Status Code | Fastly
Beyond Server Push: The 103 Early Hints Status Code | FastlyChrome and Fastly are currently running an experiment to validate a web performance tool — and we need your help! Remember all of the hype around Server Push? Since HTTP/2 shipped, it’s become increasingly clear that while the performance problem that it was designed to address is important, Server Push was not the right approach. Instead
Cache-Control in the wild | Fastly
What is Cache Control?RFC7234 defines the syntax and semantics of Cache-Control. Since I’m one of the editors currently revising the core HTTP specifications, I wanted to know how web content creators actually use Cache-Control in the wild: Do people get the syntax right? Do they use the cache directives in a clear way? I also wanted to see how common use of Cache-Control intersected with how brow

QUIC is now RFC 9000
QUIC is now RFC 9000QUIC is a new latency-reducing, reliable, and secure internet transport protocol that is slated to replace TCP, the most commonly used transport today. We’ve talked before about how we love QUIC and are deeply invested in making it a success because it aligns with our mission to build a faster, more resilient, and more trusted internet. In fact, we believe so much in the promis
Code-splitting and minimal edge latency: the perfect match
Code-splitting and minimal edge latency: the perfect matchFastly Fiddle, our code playground tool, is a React single-page app that uses the excellent Monaco IDE component that powers VS Code. Problem is, Monaco is huge. And most uses of Fiddle are read only. Do we really need to load a whole IDE to display some non-editable code? No! Is lazy loading code that's cached at the edge really fast? Yes!
State at the edge
State at the edgeIn the von Neumann model of computer architectures, a computer is defined as the combination of a logic unit — commonly, a CPU — with some form of memory, taking input and providing output. You can view the Fastly edge cloud platform as a von Neumann computer, in a way: the input and output are HTTP requests and responses; the CPU is your service configuration expressed in VCL, ou
Improving HTTP with structured header fields
Improving HTTP with structured header fieldsThe HTTP community has been busy modernising the web’s protocol over the last decade, with multiple revisions of the core specification, a number of extensions, HTTP/2, and now HTTP/3. Unfortunately, the way we define and use HTTP header fields hasn’t changed much since the beginning, with underspecified headers (and lots of different ways to handle them

The headers we don't want
Let’s look at the unnecessary headers and see why we don’t need them, and what we can do about it. Vanity (server, x-powered-by, via) You may be very proud of your choice of server software, but most people couldn’t care less. At worst, these headers might be divulging sensitive data that makes your site easier to attack. Server: apache X-Powered-By: PHP/5.1.1 Via: 1.1 varnish, 1.1 squid RFC7231 a

Solving VCL auth & feature flags at the edge | Fastly
Solving VCL auth & feature flags at the edge | FastlyIn “How to solve anything” parts 1 and 2, we outlined how to use Varnish Configuration Language (VCL) to address some of your more challenging problems. In this post, we’ll discuss how Andrew Betts of the Financial Times uses advanced VCL to securely cache and serve authenticated and authorized content, and set up feature flags. AuthenticationTo
