PerformanceResourceTiming API で HTTP Cache のヒット率を知る - Repro Tech Blog
はじめに こんにちは、Repro Booster という製品の開発責任者／プロダクトマネジメントを担当しているEdward Fox（edwardkenfox）です。 WebサイトやWebアプリケーションの表示速度を考える上では、キャッシュの活用はとても大事なテーマです。一口にキャッシュといっても、Webの文脈だけで見ても様々なレイヤーや用途のキャッシュが存在します。今回は昔ながらのキャッシュ、いわゆる HTTP Cache に的を絞り、HTTP Cache のヒット率について考えてみたいと思います。 さまざまなキャッシュレイヤー 前述のように、Webにおけるキャッシュには用途やレイヤーの異なる様々な種類のものが存在します。Webサイト／Webアプリケーションを開発する上で気にかけるべきものは、おおよそ次のようなものが該当するでしょう。 HTTP Cache （ブラウザキャッシュ） Cach

HTTP Cache で求人サイトのスピード改善を試してみた話 | MEDLEY Developer Portal
2018-08-27HTTP Cache で求人サイトのスピード改善を試してみた話こんにちは、開発本部の楊です。メドレーの社内勉強会「TechLunch」で、前回は、React の基本を紹介しましたが、今回は HTTP Cache で、医療介護求人サイト「ジョブメドレー」のスピード改善ができないか検討した話について、共有しました。 なぜ HTTP Cache について話すことにしたのかジョブメドレーには、医療機関や保育園、介護施設などさまざまな事業所の求人が掲載されています。現在、14 万を超える事業部の求人が掲載されており、かつ事業所側で求人原稿を修正することもできるため、求職者側が閲覧するスピードについては、いつも意識して改善に取り組んでいます。 その試行錯誤の中で、HTTP Cache を使って改善する方法について、実現性など含めて検証することにしました。 今回は、あるページをモデル
Increasing Application Performance with HTTP Cache Headers | Heroku Dev Center
The modern day developer has a wide variety of techniques and technologies available to improve application performance and end-user experience. One of the most frequently overlooked technologies is that of the HTTP cache. HTTP caching is a universally adopted specification across all modern web browsers, making its implementation in web applications simple. Appropriate use of these standards can
Recently we landed the new HTTP cache for Firefox ("cache2") on mozilla-central. It has been in nightly builds for a while now and seems very likely to stick on the tree and ship in Firefox 32. Given the positive data we have so far, we're taking another step today to making the new cache official: we have disabled the old APIs for accessing the HTTP cache, so addons will now need to use the cach

Here is a detailed description of the HTTP cache v2 API, examples included. This document only contains what cannot be found or may not be clear directly from the IDL files comments. The cache API is completely thread-safe and non-blocking. There is no IPC support. It's only accessible on the default chrome process.

HTTPのキャッシュをグループ化する HTTP Cache Groups の仕様 - ASnoKaze blog
『HTTP Cache Groups』という提案仕様がIETFに提出されています。これは、HTTPキャッシュをグループ化し、グループの単位で無効化や再検証を行えるようにする提案です。 Webサイトで利用する複数のJavaScriptやCSSファイルはデプロイすることがあるため、それらのキャッシュの管理をグループで扱うことはメリットがあります。例えばグループ内の一つのキャッシュを再検証(Revalidation)することで、グループ内のほかのリソースも再検証したものとして扱えるようになります。 またCDNのレイヤにおいて、キャッシュの無効化(Invalidation)・パージもグループで行えるのは管理上都合が良いでしょう。 Cache-Groups レスポンスヘッダ レスポンスにおいてCache-Groupsヘッダでグループを指定できます。 Cache-GroupsヘッダはStructure

By Ilya Grigorik on October 07, 2008 HTTP caching can go a long way to help scale a web application - instead of dynamically serving every single request, we can use memcached, Squid, Varnish, or a multitude of other tools to respond in just a few milliseconds. However, as developers at Yahoo have noted, there is a common failure scenario that is often left unaccounted for: what happens when the c
15KB Of Fame: HTTP Cache Poisoning via Host Header Injection
Personal blog of me. You can contact me through my Spock page, or my first name at bueno org. 10 June 2008 I've decided to post this here since it is pretty serious and there is no one vendor to blame. Watch yourselves.

Mozilla Firefox new HTTP cache is live! - mayhemer's blog
The new Firefox HTTP cache back-end that keeps the cache content after a crash or a kill and doesn't cause any UI hangs - has landed! It's currently disabled by default but you can test it by installing Firefox Nightly (version 27) and enabling it. This applies to Firefox Mobile builds as well. There is a preference that enables or disables the new cache, find it in about:config. You can switch i

🍰 Ease of use: Keep using the requests library you're already familiar with. Add caching with a drop-in replacement for requests.Session, or install globally to add transparent caching to all requests functions. 🚀 Performance: Get sub-millisecond response times for cached responses. When they expire, you still save time with conditional requests. 💾 Persistence: Works with several storage backen

If Firefox has been feeling sluggish for you lately, you might be able to cut down on some of those UI hangs with an about:config tweak. The Mozilla team is working on a number of performance tweaks for upcoming versions of Firefox, one of which is the use of a new HTTP cache that should fix some UI hang issues. It isn't enabled by default yet, but will be soon—and you can enable it right now with

Two ways to cache the uncacheable. Why you should not ever use expires_in inside rails to cache http request. How Nginx calcs ETag on static files and why we don’t care about it today. How correctly purge Nginx cache with one bash command. How totaly purge Rack::Cache in memcache even if it shared with Rails cache. Whats wrong with responding Cache-Control: max-age=N, where N greater than zero. Ho
