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.

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 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.
If host is omitted, it is taken to be "localhost", the machine from which the URL is being interpreted. Note that when omitting host, the slash is not omitted (while "file:///piro.txt" is valid, "file://simpen.txt" is not, although some interpreters manage to handle the latter). RFC 3986 includes additional information about the treatment of ".."
The Python Package Index appends the MD5 hash of a file to the URL as a fragment identifier. [31] If MD5 were unbroken (it is a broken hash function ), it could be used to ensure the integrity of the package.
about is an internal URI scheme (also known as a "URL scheme" or, erroneously, "protocol") implemented in various web browsers to reveal internal state and built-in functions. It is an IANA officially registered scheme , and is standardized.
URL is a useful but informal concept: a URL is a type of URI that identifies a resource via a representation of its primary access mechanism (e.g., its network "location"), rather than by some other attributes it may have. [19] As such, a URL is simply a URI that happens to point to a resource over a network.
