Here's a little more info...
The problem is that the hyphenated hostname being given to the browser
(www.first-last.com) is being changed by the servlet and the hyphen is being removed
(www.firstlast.com). (Of course that's not a real domain name but it illustrates
what's happening more clearly.) Both domains are legitimate for this server. Both are
recognized by Apache. The actual hostname (from /etc/hosts) is something completely
different.
All of this is taking place in the servlet. I haven't tested this in a jsp page.
When I give response.sendRedirect() a relative url, I notice that the hostname is
changing in the browser's location bar. Absolute urls are not a problem.
In testing, I noticed that request.getRequestURL() and request.getServerName() also
return the hostname without the hyphen.
Further testing found that request.getHeader("host") returned the correctly hyphenated
hostname given when the servlet was called by the browser.
The workaround I'm using is to build an absolute url using the hostname from the
header and redirect to that url instead of the relative url I'd been using.
Is this expected behavior? It would seem to me that the hostname given in the user's
browser's location bar should be being maintained throughout the session unless
changed by a redirection. (Which of course is what's happening.) I don't understand
why the redirection and the two request methods are dropping the hyphen. Am I doing
something wrong?
Thanks
