Inject Header Query 1.3

Inject Header Query by JkRobbin is a lightweight utility for developers and testers that lets you add, modify, or remove HTTP headers and URL query parameters before a request is sent. Create simple, reusable rules to target specific hosts or endpoints, and toggle them on or off to reproduce scenarios without changing application code. Use it to simulate user contexts and feature flags, validate caching or routing behavior, and probe how backends handle edge cases—all in a controlled, repeatable way. Use responsibly and only with systems you are authorized to test.

Common uses:

• Simulate authentication, localization, or feature flag states
• Debug API behavior without redeploying
• Validate caching, CORS, or A/B routing rules
• Reproduce hard-to-trigger bugs and edge cases
