Case 2: Remove query parameters from URL

Suppose there is a query parameter source=twitter in a URL of example.com, and you decided to remove it to anonymize yourself.

In this case, the Capturing Group Processing option is the easiest way.:

Redirect From: https://example.com/* (Wildcard)
Redirect To: $0
Capturing Group Processing:
- Group: $0
- Process: Replace Occurrences
  - Target: &?source=[^&]*
  - Replacement: (none)
  - Text Pattern: Regular Expression

This rule works as follows:

https://example.com/?source=twitter
➡️ https://example.com/?

https://example.com/?hello=world&source=twitter&foo=bar
➡️ https://example.com/?hello=world&foo=bar

If you want to remove more parameters, add more processes.
