🔗 HTTP
The target of an HTTP request is called a “resource”, whose nature isn’t defined further; it can be a document, a photo, or anything else. Each resource is identified by a Uniform Resource Identifier (URI) used throughout HTTP for identifying resources.
URLs
The most common form of URI is the Uniform Resource Locator (URL), which is known as the web address.
https://developer.mozilla.org
https://developer.mozilla.org/en-US/docs/Learn/
https://developer.mozilla.org/en-US/search?q=URL
A URL is composed of different parts, some mandatory and others optional. A more complex example might look like this:
http://www.example.com:80/path/to/myfile.html?key1=value1&key2=value2#SomewhereInTheDocument
URNs
A Uniform Resource Name (URN) is a URI that identifies a resource by name in a particular namespace.
urn:isbn:9780141036144
urn:ietf:rfc:7230
Syntax of Uniform Resource Identifiers (URIs)
Scheme or Protocol
| Scheme | Descrtiption |
|---|---|
data | Data URLs, prefixed with the data: scheme, allow content creators to embed small files inline in documents. |
file | Host-specific file names |
ftp | FTP |
http/https | HTTP, HTTPS |
javascript | URL-embedded JS code |
mailto | |
ssh | Secure shell |
tel | Phone number |
urn | Uniform Resource Name |
view-source | Source code of the resource |
ws/wss | WebSocket connections (Secure) |
Authority
Domain name or IP address.
Port
By default, :80 for HTTP and :443 for HTTPS.
Path
Path to the resource on the Web server. May or may not represent physical file location.
Query
?key1=value1&key2=value2 are extra parameters provided to the Web server. Those parameters are a list of key/value pairs separated with the & symbol.
Fragment
#SomewhereInTheDocument is an anchor to another part of the resource itself. An anchor represents a sort of “bookmark” inside the resource, giving the browser the directions to show the content located at that “bookmarked” spot.
