* Logic below identifies the type of page that is being accessed, based on the path segments that are identified, and then applies a redirect
* to the URL which is mapped to a page controller.
* For instance, a product page is identified because one of the path segments starts with "p-" and has at least 1 subsequent path (for the product id),
* and is then redirected to the product page with the product/variant id sent as query strings.
* A store page is identified with one of the segments starting with "s-" and has 1 subsequent path (for the store number).
*
* Note that this method of redirection creates a hard dependency the cutlure being explicitly passed in the URL. To account for this, we ASSUME
* that the culture is always passed as the first parameters in URL.
* This assumption is based on the ProductUrlProvider and StoreUrlProvider classes, which are responsbile for building these URLs.
