https三种实现途径(国外英文资料) Three methods HTTPS HTTPS SSL over is actually HTTP, the sender SSL protocol through the original data encryption, decryption in the receiver, so the transmitted data is not easy to hackers intercepted and crack. This paper introduces three methods of HTTPS. A method of static hyperlink This is currently used in many websites, but also the most simple. The direct indication of the use of HTTPS protocol in SSL Web transmission requires the use of Web links, the following is to use SSL web page hyperlink: SSL example That is, in the page links if you use a relative path, the transmission protocol is enabled by default agreement with reference to the hyperlink page or the same resource, such as a hyperlink in the HTTPS://00/ok/login.jps page contains the following two hyperlinks: SSL link Non SSL link So, the first link is the same as the HTTPS://00/ok/login.jsp of the HTTPS protocol, second links using the identified HTTP protocol itself. The use of static hyperlink advantage is easy to implement, without the need for additional development. However, it is not easy to maintain; because in a completely use the HTTP protocol to access Web applications, each sub directory for each resource are stored in the root directory of the application specific, link path resource use relative path, this is done in order to facilitate the application of migration and easy to management. But if some of the resources of the application to use the HTTPS protocol, the link path references must be used when complete, so the application migration or need to change if any part of the URL: domain name, directory, file name, and maintenance are required to modify each link, the workload of as can be imagined. Furthermore, if the customer in the browsers address bar manual input HTTPS protocol resources, then all sensitive data in the transmission are not protected, hackers can easily be intercepted and tamper! Two methods of resource access restrictions In order to prote
