Have you watched the construction of a big building over time? For the first few weeks, the footers and foundation are being prepared to support the building. it seems like not much is happening, but that ground work is vital to the overall success.. Read more

In this Lightboard Lesson, I light up some #basics about HTTP. HTTP defines the structure of messages between web components such as browser or command line clients, servers like Apache or Nginx, and proxies like the BIG-IP. ps Related: What is... Read more

Last week in part one of this series, we took the 50,000 foot view of the HTTP protocol. HTTP defines the structure of message transfer for web resources, but doesn’t have anything to say about or do with the underlying infrastructure (through... Read more

tl;dr - The Hypertext Transfer Protocol, or HTTP, is the predominant tool in the transferring of resources on the web, and a "must-know" for many application delivery concepts utilized on BIG-IP HTTP defines the structure of message... Read more

In this article, I will give an overview of some important headers that can be added to HTTP responses in order to improve the security web applications. Read more

What could you do with your code in 20 Lines or Less? That's the question we like to ask from, for, and of (feel free to insert your favorite preposition here) the DevCentralcommunity, and every time we do, we go looking to find cool new... Read more

From HTTP to SPDY, to HTTP 2.0. The introduction of a new protocol optimized for today’s evolving web services opens the door to a world of possibilities. But are you ready to make this change?While the breakneck speed with which applications,... Read more

HTTPからSPDY、そしていよいよHTTP2.0へ ― 進化するウェブサービス最適な最新のウェブのプロトコル導入を見据え、様々な取り組みが始まっています アプリケーション、デバイス、サイバーセキュリティの進化は目まぐるしく進んでいますが、インターネットの大部分の通信を担う通信プロトコル「HTTP」は実は初代からあまり大きな進化を遂げていない ― これは意外と知られていない現実です。 インターネット標準化団体であるIETFの資料によると、初代のHTTP... Read more

#SDN #webperf  It means you can't use "network" protocols to make intelligent decisions about applications any more. Back in 2000 (or 2001, I forget exactly), I got to test a variety of bandwidth management appliances. Oh, they... Read more

Much is being written lately about so-called "Zero Trust Model" security, which prompts me to ask, "Since when did we security folk trust anyone?"  On the NIST site, you'll find a thorough report NIST commissioned from... Read more

#sdas #devops #webperf Speaking "HTTP" doesn't make you application fluent, it makes you protocol fluent. There are over a million apps in the Google Play Store. There are also about a million apps in the Apple App Store. That's... Read more

#SDN To really provision bandwidth efficiently you have to get inside the application. One of the most commonly cited use cases for SDN (the classical, architectural definition) centers on ensuring quality of service for applications, usually by... Read more
