Content delivery networks (CDNs) | Articles | web.dev
Content delivery networks (CDNs) Stay organized with collections Save and categorize content based on your preferences. Content delivery networks (CDNs) improve site performance by using a distributed network of servers to deliver resources to users. Because CDNs reduce server load, they reduce server costs and are well-suited to handling traffic spikes. This article discusses how CDNs work and pr
Static Hoisting
Static Hoisting@rauchg|May 2, 2020 (4y ago)36,673 views Since I published my 2019 in Review, detailing the industry trend towards static hosting and the rise of Jamstack CDNs like Vercel, a question has persistently come up: how is this different from a server and a traditional CDN on top? Why not then just use servers with containers (even serverless ones)? The answer boils down to our ability to
Experiment with HTTP/3 using NGINX and quiche
Just a few weeks ago we announced the availability on our edge network of HTTP/3, the new revision of HTTP intended to improve security and performance on the Internet. Everyone can now enable HTTP/3 on their Cloudflare zone and experiment with it using Chrome Canary as well as curl, among other clients. We have previously made available an example HTTP/3 server as part of the quiche project to al
Use image CDNs to optimize images | Articles | web.dev
Use image CDNs to optimize images Stay organized with collections Save and categorize content based on your preferences. Image content delivery networks (CDNs) are excellent at optimizing images for the web. Switching your website to an image CDN can yield a 40–80% savings in image file size, and in most cases they can optimize your images better than a build-time image optimization script. What's

キャッシュがHitした情報を示すCacheヘッダの標準化提案 - ASnoKaze blog
20191104 追記 draft 01でCache-Status に改称されるとともに、内容も変わりました 更新記事を書きました asnokaze.hatenablog.com CDNなどのサービスは、リクエストがキャッシュにヒットしたかどうかをx-cacheヘッダに格納してレスポンスしてくれます このx-cacheヘッダは独自の形式であり、例えば以下のようになっています。 （CDNによっては、x-cache以外のヘッダを使うものもあります） fastly (document) X-Cache: MISS, HITAmazon CloudFront X-Cache: Hit from cloudfront先述のように、x-cacheヘッダは標準化されておらずCDN毎に独自に使用されています。 そこで、IETFのHTTbisにおいて キャッシュのHit情報などを格納するcacheヘッダの標

コンテンツキャッシュとVaryヘッダとnginx - Qiita
Varyヘッダは前段のキャッシュサーバに対して、指定したヘッダの内容ごとにキャッシュを分ける必要があることを伝えるためのものです。例えばサーバがVary: Accept-Encodingをレスポンスヘッダに付加しておくと、キャッシュサーバはAccept-Encodingヘッダの内容に応じたキャッシュを保持します。 こうすることでクライアントのAccept-Encodingヘッダの内容に応じたキャッシュデータをキャッシュサーバは返すことができるというわけです。 nginxにおけるgzip圧縮とVaryヘッダ さて、本題です。上記のような事情からかApacheのmod_deflateやh2oなんかはコンテンツのgzip圧縮を有効にすると、自動的にVary: Accept-Encodingをレスポンスヘッダに付加します。一方我らがnginxは設定ファイルにgzip_vary on;と書かないとV
