Recall that in a REST service, URLs represent objects, and HTTP methods represent
verbs that act on those objects. Thus, the weather service's URL is really a prefix to a spe-
cific object; accessing the web service for the weather in Berkeley, California, the
application might generate this URL:
http://www.noplace.com/location/Berkeley%2C%20CA%2C%20USA
