Dynamic value
ModHeader supports simple dynamic value substitution. In the value fields, if you enter one of these special strings, the values will be replaced at runtime:
{{uuid}}
- A random UUID v4{{url}}
- The current request URL{{url_origin}}
- The current request URL's origin{{url_hostname}}
- The current request URL's hostname{{url_path}}
- The current request URL's path{{url_query.<query_name>}}
- The current request URL's query parameter's value. For example, if the request URL ishttps://example.com/?foo=bar
, and the dynamic string is{{url_query.foo}}
, then it will be evaluated tobar
at runtime.{{url_query.<query_name>}}
requires ModHeader v4.3.2+
{{existing_value}}
- The existing value (if any){{timestamp}}
- The current time (in milliseconds since epoch){{ip_v4}}
- A random IP v4 value
