What a user types to reach a resource
Understanding each component:
**Scheme**: | | identifies the protocol being accessed by the client.
**User Info**: | admin:password@ | Optional, used to authenticate to a host.
**Host**: | inlanefreight.com | Resource location, can be either a hostname or an IP address.
**Port**: | :80 | When no port is specified, http will go to 80, https will go to 443.
**Path**: | /dashboard.php | The resource being accessed. Can be a file or folder. Will go to default index. ex: index.html
**Query String**: | ?login=true | Consists of paramater (login) and value (true). Multiple parameters can be used if seperated by &.
**Fragments**: | #status | Processed by the browser on the client-side to locate sections within the primary resource. (ex: header or section on the page).
All components are not necessary to reach a resource. Mandatory fields include the **scheme and host**.
