One other point to consider is that adding a parameter to the request could
result in multiple single parameter values if the parameter already existed in
the request. Depending on your app, you may or may not want that, but it could
be useful if you needed to retain previous values for a given parameter. There
are arguably better ways to get the same result, but it could be used for
example for something like building a breadcrumb trail in simple apps.
