web protocols

script contains the detailed information of the data requested by your browser, rather than the operation process information. The Web (HTTP/html) protocol provides two recording methods: HTML-based and URL-based. These two methods allow you to specify the information to be recorded and the functions used by the script. For example, when you click the button (whether it is an image or a button) to submit information, vugen will generate the web_submi

I. Summary This article compares the transmission performance of five communication protocols, including RMI, Hessian, burlap, httpinvoker, and Web Service, in different data structures and data volumes. RMI is a remote communication protocol provided by the Java language. It is stable and efficient and is the basis of EJB. But it can only be used in Java Program Communication. Hessian and burlap are open

First, Web applications　　A Web application is an application that can be accessed through the web;The biggest benefit of the program is that the user has easy access to the application, and the user needs only a browser and no additional software to install.There are two modes of application: C/S,/b.1, c/S is a client/server-side program, which means that such pr

Logging-Logs the completed HTTP transaction into the log fileThere may be multiple Web resources in a page requested by the user, each of which is to be requested separately, and the HTTP protocol is based on the TCP protocol, which requires three handshakes per connection and four disconnects when disconnected, which is a waste of time and bandw

reasonable optimization, HTTPS machine costs will not increase significantly. For small and medium-sized websites, there is no need to add machines to meet performance requirements.PostscriptMany foreign large Internet companies have enabled the full-site HTTPS, which is the trend of the Internet in the future. The large domestic internet does not deploy HTTPS all the time, but HTTPS is enabled on some sub-pages/sub-requests involving accounts or transactions. Baidu search for the first full-si
