Headers
Mokku lets you modify any request header — applies to API calls and resource requests alike. Rules can target a specific URL, a URL pattern, or an entire origin.
Add a Header Rule
Go to the Headers section, select a project, then click Add Header.
Configure:
- Action — Set, Append, or Remove
- Header name — the header to target
- Value — what to set or append (not needed for Remove)
- URL / Origin filter — scope the rule to a specific URL or origin
URL Rules
Header rules use Chrome’s declarativeNetRequest URL filter syntax.
