Use Apache HTTP Client 4.X to set your location on google and execute a search request

The new google search engine results page has a form where you can set your location. The location setting issues a request that looks a bit like this: [login to view URL] the luul parameter is the zip code. I entered 94002. Depending on the location, the search results page will list different results. I am NOT looking for a way to form the query like this: [login to view URL] this will NOT return the same results as setting the location via the change location link on the SERP and resubmitting a query.
