Summary

Currently, Shlink does not allow setting an empty query parameter value when creating redirect rules. For example, xxx.com?test is not possible, as a value is required. It would be useful to allow parameters without values.

Use case

Some APIs or services expect query parameters without values (e.g., ?debug or ?feature).

Certain tracking or feature flag implementations rely on the presence of a parameter, regardless of its value.

This would improve flexibility when setting up redirect rules.
