Subject Re: servlet URL
Date Fri, 07 Feb 2003 19:24:12 GMT
  Sorry, context-parameter? But then I wouldn't have (again) my
servlet's URL written in two different places? This kind of thing
worries me, because somebody can change in one place but not on another.
  I think I can understand the HttpServletRequest way of doing it... but
then I could only determine after my servlet is first called, right?
  Anyway, how I would do that? Getting all bytes from the string from
the beginning 'till the end or '?' character?
