A query string is a part of a uniform resource locator that assigns values to specified parameters.A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.
A URL will often comprise a path, script name, and query string. The query string parameters dictate the content to show on the page, and frequently include information opaque or irrelevant to users—such as internal numeric identifiers for values in a database, illegibly encoded data, session IDs, implementation details, and so on.

The site can continue to use the same URLs even if the underlying technology used to serve them is changed (for example, switching to a new blogging engine). There can, however be drawbacks as well; if a user wants to modify a URL to retrieve new data, URL rewriting may hinder the construction of custom queries due to the lack of named ...
A uniform resource locator (URL), colloquially known as an address on the Web, [1] is a reference to a resource that specifies its location on a computer network and a mechanism for retrieving it. A URL is a specific type of Uniform Resource Identifier (URI), [2] [3] although many people use the two terms interchangeably.
A framework's URL mapping or routing facility is the mechanism by which the framework interprets URLs. Some frameworks, such as Drupal and Django, match the provided URL against pre-determined patterns using regular expressions, while some others use rewriting techniques to translate the provided URL into one that the underlying engine will ...
Django (/ ˈ dʒ æ ŋ ɡ oʊ / JANG-goh; sometimes stylized as django) [6] is a free and open-source, Python-based web framework that runs on a web server. It follows the model–template–views (MTV) architectural pattern .
Therefore, URLs are a subset of URIs, ie. every URL is a URI (and not necessarily the other way around). [2] Other URIs provide only a unique name, without a means of locating or retrieving the resource or information about it; these are Uniform Resource Names (URNs). The web technologies that use URIs are not limited to web browsers.
A Uniform Resource Name (URN) is a Uniform Resource Identifier (URI) that uses the urn scheme.URNs are globally unique persistent identifiers assigned within defined namespaces so they will be available for a long period of time, even after the resource which they identify ceases to exist or becomes unavailable.
