What is a URL?
A URL (Uniform Resource Locator), commonly called a web address, is the complete reference used to locate resources on the internet (e.g., websites, images, APIs).
Structure of a URL:
A typical URL consists of these components:
https://www.example.com:443/path/to/page?query=value#section
- Protocol (https://) – Encryption & communication rules (HTTP/HTTPS).
- Domain (www.example.com) – Website’s unique identifier.
- Port (:443) – Optional gateway for server access (HTTPS defaults to 443).
- Path (/path/to/page) – Specific resource location on the server.
- Query (?query=value) – Parameters sent to the server (used in tracking).
- Fragment (#section) – Scrolls to a page section (client-side only).
Why URLs Matter in Privacy and Anti-Detection
URLs can leak sensitive data or contribute to device fingerprinting through:
- Tracking parameters (e.g.,
?utm_source=facebook). - Unique session IDs embedded in paths.
- Referral headers exposing browsing history.
URL Best Practices for Secure Browsing
- Use HTTPS for encrypted connections.
- Avoid clicking on suspiciously long or parameter-heavy URLs.
- Leverage anti-detect browsers like FlashID to compartmentalize browsing activities.
