This plugin solves a problem that occurs when using the back button of the browser, in conjunction with active infinite scrolling. Scrolling down the category page will load more products (if any). If you subsequently visit a product page and then press the back button of the browser, you will not end up as expected at the point where you have previously clicked the product.
The plugin solves this problem by adding another parameter on the current URL after clicking on a product. The old URL will be replaced by the new URL in the browser history. If you press the back button from the product page, the set parameter will be recognized. As a result, the browser jumps to the point oft he category page where the previously clicked product is located. The same problem also existed when using the search and is also resolved with this plugin.
