HTTP vs HTTPS
Mr. Licklider had proposed a solution, it was Galactic Network. This type of network would allow the government leaders to communicate if Soviets did destroy the telephone system. In 1965 there was another M.I.T Scientist by the name of Leonard Kleinrock, he is considered one other father of the Internet. The reason he considers a father of the Internet is because he developed a network called packet-switching.
Toward the end of 1969 only four computers were connected to ARPnet network, but by 1970 the network was growing. Also in the 1970 another computer scientist by the name of Vinton Cerf. Mr. Cerf from the years of 1976-1982, Mr. Cerf. was a program manager with the U.S. Department of Defense’s Advanced Research Projects Agency (DARPA), this is where he fostered the development of Internet-related packet data and security technologies. During the same year, the University of Hawaii had installed ALOHnet, and two years London University college and Royal Radar Establishment in Norway. The packet-switched has multiplied networks but became much more difficult to integrate into a single internet. Also in 1992, Mr. Cerf founded the Internet Society. For 1992-1995, Mr. Cerf was also the president.
Netscape allowed people to access the Internet and see words and pictures on the same page at the same time, have clickable links, and navigate with a scrollbar. Also Congress would use the web to promote their commercials, because of that everyone with a web site would do the same. This became a good way to reach customers and sell goods. Each page exists because of Hypertext Transfer Protocol (HTTP). HTTP was proposed by Mr. Berners-Lee.
HTTP is the common language, for the World Wide Web (WWW). WWW is making up the modern web. The reason for developing HTTP is so that is would work with easily with other browsers. The HTTP will start off as a single keyword, and Document path, for browsers, and Internet-connecting software and hardware application. Mr. Berners-Lee outlined the motivation for the new protocol, and was listed with high-level design goals they include; file transfer functionality, request an index search of a hypertext archive, format negotiation, and refer the client to another server. A simple prototype was built. It implemented a small subset of proposed function, they include; a client requests a single ASCII character string also, terminated by a carriage return (CRLF), server response in an ASCII character stream, a hypertext markup language (HTML), and a connection is terminated after the document transfer is complete.
This path id a single line: GET method, it is the response to a single hypertext document. Meaning, no heading, or other Metadata, only the HTML tag. Using this type of tag it the 0.9 version of HTTP. (Below is an early version of HTTP using the GET method.)
In 1991, 0.9 version of HTTP became its own and evolved rapidly over the coming years. The 0.9 version offers Client-server, request-response protocol, ASCII protocol, running over a TCP/IP link, designed to transfer hypertext documents (HTML), and the connection between server and client is closed after every request, it used web servers like Apache and Nginx. After 0.9 version came the 1.0 Rapid growth and informational (RFC).
The 1.0 Rapid growth and informational (RFC) had its highest points from 1991-1995. During this time National Center of Supercomputing Applications (NCSA), came up with their own version of the RFC. Sometime in October of 1994 a programmer that was a part of NCSA team, Marc Andreessen, partnered with Jim Clark and together they formed, a Mosaic Communications, which was the early version of Netscape. Also, there was a World Wide Web conference located in Geneva, Switzerland. Because of the conference the World Wide Web Consortium. W3C help formed HTML.
Around the same time a parallel HTTP Working Group (HTTP-WG), the IETF focus on improving HTTP protocol. Through the years of 1994-1995 there was a dial-up Internet access for the public. On August 9, 1995, was the first day of the Internet along with it popularity. With the web growing, a community of web developers produced a large number of experimental HTTP server and client implementations through an ad hoc process: implement, deploy, to see if others adopt it.
In May 1996 the HTTP Working Group (HTTP-WG) published RFC 1945, which documented the “common usage” of the many HTTP/1.0 implementations found in the wild, which was a period of rapid experimentation, with the best practices along with common patters.
o Request line with HTTP version number, followed by request headers Response status, followed by response headers
The Exchange is not an in-depth list of HTTP/ 1.0 capabilities some key protocol changes are; Request may consist of multiple newline separated header fields. The response object is prefixed with a response status line, response object has its own set of newline separated header fields, the response object is not limited to hypertext, and the connection between server and client is closed after every request.
HTTP 1.1 is an official IETF internet standard. Between the years of 1995- 1999 produced the first official version of HTTP was released. Some of the early version introduced a number of critical performance optimizations: alive connections, chunked, encoding transfer, byte-range requests, additional caching mechanisms, transfer encodings, and request pipelining.
When an HTTPs is requested the website will initially send its SSL certificate to the browser. a certificate contains the public key needed to begin the secure session. Based on this initial exchange, the browser and the website then initiate the ‘SSL handshake’. The SSL handshake involves the generation of shared secrets to establish a uniquely secure connection between the personal computer and the website. When a trusted SSL Digital Certificate is used during a HTTPS connection, users will see a padlock icon in the browser address bar. When an Extended Validation Certificate is installed on a web site, the address bar will turn green.
All communications sent over regular HTTP connections are in ‘plain text’ and can be read by any hacker that manages to break the connection between the browser and the website. This presents a clear danger if the ‘communication’ is on an order form and includes a personal credit card details or social security number. a HTTPS connection, all communications are securely encrypted. This means that even if somebody managed to break the connection, they would not be able to decrypt any of the data which passes between you and the website.
