/**
* Get Address servlet. This servlet saves the information from a from
* to a log file and serves up a file provided the required fields were
* entered. If not a page with a message to go back and give the required
* fields is served.
*
* There are 2 init parameters:
*
* servedfile the file served if the info is ok
* logfile file where the info is logged
*
* servedfile must either start with http: (and be a
* valid URL in this case) or be an absolute path starting with a /.
* In either case it must be a valid html page.
