URL Parameter

A URL parameter (also known as a query string) is the part of a URL that follows a question mark (`?`), used to pass data to the server (e.g., `?utm_source=google`). Parameters used for tracking, sessions, or analytics can be problematic for caching, as they create many unique URLs that all point to the same content, reducing the cache-hit ratio. Speed Kit can be configured to ignore specific, non-essential parameters, allowing it to treat these different URLs as a single cacheable item.
