the site and the performance of the server consumption. Let's look at some of the problems that HTTPS faces. HTTPS multiple handshake, will reduce the user access speed to some extent After the site has switched to HTTPS, the way HTTP jumps to HTTPS increases user access time (most sites use 301, 302 jumps) HTTPS involves a security algorithm that consumes CPU resources and requires a large number of machines to be added (HTTPS access processes need to be decrypted) SSL cer

Bloggers before the article is to teach you how to quickly build a fabric environment, but a lot of work has been hidden in the official script, it is not convenient for us to understand the process in depth, so bloggers here will be the process of one step by step decomposition, to facilitate everyone. In front of the preparation I don't have to say, that is, the installation of various software and development environment, after installation, we git clone down the latest code, and switch to v1

libraries and executables, respectively. They enable the intermediate code generated during the compilation phase to have the attribute of address-independent code. However, this does not mean that the last generated executable file is pie. You also need to tell the linker to generate an executable program of address-independent code at link time through the-pie option.A standard PIE program compiles the following settings:-o sample_pie sample.-fPIE-pieThe corresponding relationship between usi

Basic knowledge Preparation: Before you understand the fundamentals of HTTPS, you need to understand the basics below.First, what is Https,tls,sslHTTPS, also known as HTTP over TLS. The predecessor of TLS is SSL,TLS 1.0, which is typically marked as SSL 3.1,TLS 1.1 for SSL 3

Windows 2 k DLL Loading ProcessJefong by 2005/03/30This article is my summary after reading MSJ September 1999 under the hood.In Windows, the EXE executable program calls some DLL, such as kernel32.dll and user32.dll. But how is the DLL loaded? Generally, we all know that there will be a dllmain entry function when writing a DLL, but in fact this function is not the first job to call the DLL. First, the DLL needs to be loaded, and then initialize and allocate the DLL before entering the dllmain.

1 SPDY protocol 1.1 Overview SPDY is the abbreviation of speedy, which is the pronunciation of speedy. The SPDY protocol has published four drafts: Version 1, version 2, version 3, and Version 3.1. Version 4 is currently in the trial phase, but has not yet been released. There are some code for version 4 in Chromium. Advantages of SPDY over HTTP: Disadvantages: Due to these disadvantages, SPDY is less effective on small websites (with a small number of resource files) and may be slower than mult
