Combination
Ajax is a web development technique for dynamically interchanging content which sends a request to the server for data. The server returns the requested data which is then formatted by a client side script. This technique reduces server load time because the client does not request the entire webpage to be regenerated by the server's language parser; only the content that will change is transmitted. Google Maps is an example of a web application that uses Ajax techniques.
A Web client program (such as a web browser) can access data from many different servers, such as Gopher, FTP, NNTP (Usenet) or HTTP. The HTTP server was designed specifically for the Web, and employs a protocol (system of messages) that supports sending documents from the server to a browser, and that also support sending complex data from the client back to the server. There are several HTTP methods for doing this (in HTTP, methods is a technical term for the way in which data are sent between a client browser and server).

Famous quotes containing the word combination:
“Hats have never at all been one of the vexing problems of my life, but, indifferent as I am, these render me speechless. I should think a well-taught and tasteful American milliner would go mad in England, and eventually hang herself with bolts of green and scarlet ribbon—the favorite colour combination in Liverpool.”
—Willa Cather (1876–1947)
“Never support two weaknesses at the same time. It’s your combination sinners—your lecherous liars and your miserly drunkards—who dishonor the vices and bring them into bad repute.”
—Thornton Wilder (1897–1975)
“We attempt to remember our collective American childhood, the way it was, but what we often remember is a combination of real past, pieces reshaped by bitterness and love, and, of course, the video past—the portrayals of family life on such television programs as “Leave it to Beaver” and “Father Knows Best” and all the rest.”
—Richard Louv (20th century)
