First of all, let's understand the difference between HTTPS and http, and understand why HTTPS encryption is necessary for network security. HTTPS is a secure HTTP channel, in short, a secure version of HTTP. That is to say, the SSL layer is added under HTTP, and the security foundation of HTTPS is SSL, so the detailed content of encryption requires SSL. It is a URI scheme (abstract identifier scheme) with a syntax similar to the http: scheme. HTTPS: The URL indicates that it uses HTTP, but HTTPS has a different default port than HTTP and an encryption/authentication layer (between HTTP and TCP). This system was originally developed by Netscape, which provides authentication and encrypted communication methods. Now it is widely used for secure and sensitive communication on the World Wide Web, such as transaction and payment. The confidential mailboxes of some enterprises will use HTTPS encryption. There are some online banking sites, Alipay, Tenpay and other financial sites generally use HTTPS sites for security.
The problem of domain name redirection is a key issue. Old users of the website are very familiar with the website and are accustomed to using http access. If there is no redirection, the website is likely to be inaccessible. This is the site owner and user. You don't want to see it. Therefore, redirection can also make a good connection and transfer of the weight of the website, without causing weight dispersion.
2. Link publishing problemAfter a website is installed with an ssl certificate, when publishing external information through the media, the link must be mainly HTTPS. Nowadays, people's understanding of these two points is not complete, and many users do not care whether your site is an https site or not, but in In the future, the popularity of the site will make users start to pay attention. If the external links can be laid out in advance, it should be beneficial for the website.
3. Affiliate link problemWhen a website exchanges friendly links, it is best to choose an HTTPS website for the exchange, which can increase the favorability from the perspective of optimization.
Baidu has opened the collection of HTTPS sites. HTTPS sites can be successfully crawled by Baidu without any additional work. Baidu has already adopted site-wide HTTPS encryption. The HTTPS encryption mechanism and authentication mechanism can reduce website access. Risk of hijacking and impersonation, so HTTPS is very important for websites.
