You can use a URL match in combination with a funnel to match URLs which contain query string params. In this example we are going to explore how to match against the following URL:/product?category=parachutes
First we are going to match the path portion of the URL with the following URL match: /product.
While the URL match will correctly match /product?category=parachutes it will also match other unwanted URLs like no query string params /product or the wrong query string params /product?category=bananas etc. To fix this we are going to add a funnel directly after the URL match to restrict the query string params that we accept.
