What is User-agent Spoofing?
User Agent Spoofing is a technique used by web browsers and other software to disguise their identity. By altering the User Agent string, a browser can present itself as a different browser, version, or operating system. This can be used for various reasons, such as:
- Privacy: Users may spoof their User Agent to prevent websites from tracking their browser or system specifics.
- Compatibility: Some users may need to spoof their User Agent to access content or features optimized for different browsers or devices.
- Testing and Development: Developers may use User Agent spoofing to test how their websites behave across different browsers and devices without switching hardware.
