A chrome extension for overriding external http request headers and query parameters
Request Header/Query Param Override MV3 Extension
The extension allows the user to manage request headers/query params that will be injected into requests made when viewing a website in chrome, where each override contains the following properties:
* Header/Query Param: Header key.
* Header/Query Param Value: Value associated with the header key.
* AJAX Request URL sub-string: The header name: value will only be applied to XHR/Fetch requests where the external request URL contains the provided substring.
The headers are managed in the chrome extension popup (a simple react app), and saved to chrome local storage and are applied to upstream page requests using the chrome declarativeNetRequest request dynamic rules updateDynamicRules function.
This is a free extension, and will always be free :)
