In the World Wide Web, a query string is the part of a Uniform Resource Locator (URL) that contains data to be passed to web applications such as CGI programs.
When a web page is requested via the Hypertext Transfer Protocol, the server locates a file in its file system based on the requested URL. This file may be a regular file or a program. In the second case, the server may (depending on its configuration) run the program, sending its output as the requested page. The query string is a part of the URL which is passed to the program. Its use permits data to be passed from the HTTP client (often a web browser) to the program which generates the web page.

Famous quotes containing the words query and/or string:
“Such condition of suspended judgment indeed, in its more genial development and under felicitous culture, is but the expectation, the receptivity, of the faithful scholar, determined not to foreclose what is still a question—the “philosophic temper,” in short, for which a survival of query will be still the salt of truth, even in the most absolutely ascertained knowledge.”
—Walter Pater (1839–1894)
“The string quartet plays for itself,
gently, gently, sleeves and waxy bows.”
—Anne Sexton (1928–1974)
