/**
|
|
* Mutates the provided URL by adding a cache-busting search parameter for CDNs that don't
|
|
* support custom headers. This helps avoid caching conflicts by making each request unique.
|
|
*
|
|
* Rather than relying on the Vary header which some CDNs ignore, we append a search param
|
|
* to create a unique URL that forces a fresh request.
|
|
*
|
|
* Example:
|
|
* URL before: https://example.com/path?query=1
|
|
* URL after: https://example.com/path?query=1&_rsc=abc123
|
|
*
|
|
* Note: This function mutates the input URL directly and does not return anything.
|
|
*
|
|
* TODO: Since we need to use a search param anyway, we could simplify by removing the custom
|
|
* headers approach entirely and just use search params.
