I watched a discussion about X-Cache and X-Cache-Lookup headers unfold recently and it turns out a lot of people who I would have thought knew what these headers were indicating were a little muddled up. Further more, it turned out if you go looking for a good explanation, everyone seems to just link to this rather old blog post - despite being well meaning, it’s unfortunately slightly confused to

1. Caching set cookies Caching an object with a Set-Cookie header can have devastating effects, as any client requesting the object will get that same cookie set. This can potentially lead to a session transfer. In general we recommend avoiding the use of return (deliver) in vcl_fetch, to stay safe against this. If you really do need a return (deliver), be careful and check for the presence of Set
As shown above, the browser sends a lot of information along with the URL. The Accept header tells you what sort of content the browser prefers, User-Agent specifies which version of what browser it is, Accept-Language contains a list of languages (and dialects) that the user has configured, and Accept-Encoding shows which compression schemes the browser supports. For practical purposes, we only c
Device detection¶ Device detection is figuring out what kind of content to serve to a client based on the User-Agent string supplied in a request. Use cases for this are for example to send size reduced files to mobile clients with small screens and on high latency networks, or to provide a streaming video codec that the client understands. There are a couple of strategies on what to do with such
HTTP pipelining is a feature of HTTP/1.1, which allows multiple HTTP requests to be sent over a single TCP connection without waiting for the corresponding responses.[1] HTTP/1.1 requires servers to respond to pipelined requests correctly, with non-pipelined but valid responses even if server does not support HTTP pipelining. Despite this requirement, many legacy HTTP/1.1 servers do not support pi
HTTP Strict Transport Security (HSTS) is a policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks[1] and cookie hijacking. It allows web servers to declare that web browsers (or other complying user agents) should automatically interact with it using only HTTPS connections, which provide Transport Layer Security (TLS/SSL), unlike the in
2012/03/28 ログインや入力フォームなどが含まれないページも含め、Webサイト全体のSSL化を検討してほしい――日本ベリサインは3月28日、常時SSL(Always-on SSL)に関する説明会を開催した。 米シマンテック シマンテックトラストサービシズ プロダクトマーケティング シニアディレクターのロブ・グリックマン氏は、「Webサイトのセキュリティはクリティカルな問題になっている」と述べ、主に2つの攻撃シナリオがあると説明した。 1つは、正規のWebサイトが攻撃者に乗っ取られて、アクセスしてきたユーザーにマルウェアを仕込んでしまうケース。もう1つは、通信経路で盗聴した情報によるなりすまし(セッションハイジャック)だ。 特に後者の問題に対する「簡単かつコスト効率に優れた解決策が、常時SSLだ」(グリックマン氏)という。すでに、FacebookやTwitter、Google、Pay
Quick News Dec, 5th, 2023 : HAProxy 2.9.0 release This release has received a lot of small changes that are difficult to summarize. Most of them were aimed at improving performance and resource usage in general (zero-copy forwarding, QUIC's smaller footprint for closed connections, improved scalability), others focusing on better integration with other components (support for the AWS-LC crypto lib

Web application firewalls provide security at the application layer. Essentially, WAF provides all your web applications a secure solution which ensures the data and web applications are safe. A web application firewall applies a set of rules to HTTP conversation to identify and restrict the attacks of cross site scripting, SQL injections etc. You can also get web application framework and web bas
a cheesy Apache / IIS DoS vuln (+a question) From: Michal Zalewski <lcamtuf () dione ids pl> Date: Thu, 4 Jan 2007 00:27:11 +0100 (CET) I feel silly for reporting this, but I couldn't help but notice that Apache and IIS both have a bizarro implementation of HTTP/1.1 "Range" header functionality (as defined by RFC 2616). Their implementations allow the same fragment of a file to be requested an arb
