モバイルウェブ環境のHTTPSのチューニング « NAVER Engineers' Blog
こんにちは検索サービス開発４チームの崔珉秀と申します。 インフラやシステムとの連携や統計のバックエンドを担当しております。 モバイルのウェブ環境はPCのウェブ使用環境とは色々な違いが有ります。 ネットワークの速度だけではなくバッテリーの効率を考えた仕組みなど、PCに比べリソースが十分ではないためモバイルブラウザの動作が異なっていることも有ります。 今回はモバイルのウェブApplicationにおけるSSL関係の性能に関する工夫の内容をQ&A形式で解説していきます。 Q. 何が問題でしたか？ A. モバイルクライアント(iPhone, Android)のアプリケーションからのHTTPリクエストの応答時間に遅延の問題が有ります。 最初はweb access logからのslow response(１秒以上)のHTTPリクエストが結構ありました。 そのHTTPリクエストをprotoc
nextthing.org » Fun With HTTP Headers
Introduction Like any good web developer, I have a tendency to poke around at people’s web sites to see if I can figure out how they’re implemented. After poking at enough sites, I started noticing that people were putting some weird and interesting stuff in their HTTP headers. So, a couple of weeks ago, I decided to actually go out and see what I could find by scrounging around in HTTP headers in

Masking Latency & Failures with Squid - igvita.com
By Ilya Grigorik on August 05, 2009 Latency matters. Watching the interviews with the Yahoo developers on the launch of their new homepage, I was once again reminded about the great amount of effort they have put in to make it all work. In fact, I've written about Mark Nottingham's proposals for stale-while-revalidate and stale-if-error in the past (with a homebaked implentation), but a more reali

Protecting Your Cookies: HttpOnly
28 Aug 2008 Protecting Your Cookies: HttpOnly So I have this friend. I've told him time and time again how dangerous XSS vulnerabilities are, and how XSS is now the most common of all publicly reported security vulnerabilities -- dwarfing old standards like buffer overruns and SQL injection. But will he listen? No. He's hard headed. He had to go and write his own HTML sanitizer. Because, well, how
High Performance Web Sites
14 Rules for Faster-Loading Web Sites These rules are the key to speeding up your web pages. They've been tested on some of the most popular sites on the Internet and have successfully reduced the response times of those pages by 25-50%. The key insight behind these best practices is the realization that only 10-20% of the total end-user response time is spent getting the HTML document to the brow
仙石浩明の日記: stone に Server Name Indication (TLS 拡張) 機能を実装
このハンドシェークの後、 クライアントが暗号化された http リクエストを送信し、 それを受けてサーバが暗号化されたレスポンスを返す。 https サーバがバーチャルドメイン機能を持つには、 https サーバがサーバ証明書を送信する (上のハンドシェーク図の 3行目) より前に、 クライアントがリクエストしたいホスト名を通知する必要がある。 上図から明らかなように、 ホスト名の通知は一番最初の「ClientHello」で行なわれなければならず、 そのための拡張が、 「Server Name Indication」というわけである。 もちろんこの時点では、まだ鍵の交換は行なわれていないので、 ホスト名は平文で送られる。 前置きが長くなってしまったが、 この Server Name Indication (SNI) を stone でサポートしてみた (stone.c Revision 2
Asynchronous DB: DBSlayer & HTTP - igvita.com
By Ilya Grigorik on August 11, 2008 You hit a web 2.0 nerve and that magical 'viral coefficient' is working with full force, except now you' have a problem: scaling the database. No problem, you say, we have a few tricks up our sleeve: faster disks, loads of memory, dataset sharding, load balancing, connection pooling, master-master and master-slave replication schemes, multiple caching layers...
webhooks / FrontPage
What is a WebHook? The concept of a WebHook is simple. A WebHook is an HTTP callback: an HTTP POST that occurs when something happens; a simple event-notification via HTTP POST. A web application implementing WebHooks will POST a message to a URL when certain things happen. When a web application enables users to register their own URLs, the users can then extend, customize, and integrate that app
