URL Structure and Components

A URL (Uniform Resource Locator) is composed of several distinct components that together identify and locate a specific resource on the internet.

Anatomy of a URL

scheme://username:password@host:port/path?query#fragment — Each component is optional (except scheme and host). The port is omitted when using the default for the scheme (80 for HTTP, 443 for HTTPS). Fragments are not sent to the server — they are processed entirely by the browser.

Query string encoding

Query parameter values must be percent-encoded to escape characters with special meaning. Space → %20 (or +), & → %26, = → %3D. The URLSearchParams API handles encoding and decoding automatically. Manually concatenating query strings without encoding causes parsing errors and security vulnerabilities.

URL canonicalization for SEO

Search engines treat http://example.com, https://example.com, and https://www.example.com as separate URLs that may contain duplicate content. Canonical URLs use the rel="canonical" link tag to tell search engines which version is authoritative, consolidating link equity.

Common questions

Frequently asked questions

Does it decode percent-encoded parameters?

Yes, query values are automatically decoded so you see the readable version rather than the raw percent-encoded form.

What if the URL has no protocol?

A protocol-relative or bare domain input is flagged, since a complete URL requires an explicit scheme to parse correctly.
