RE: problem in getHeader()
Uhh, headers don't work that way. You send headers to help the
browser and network know what they are working with. The browser sets the
headers for the new request to help you and the network deal with the
request. One set of headers has no bearing on any others.

Re: Problem with getHeader(Referer)
I'm going to the page via a link, not dialing direct. Both methods leave with with
a result of null;

Going from page1 to page2 should result in "page1.yourextension" being written
to the screen.
Hitting ^L (YMMV) or typing page2.jsp into your address bar will result in the
second message.
Does that help?

Subject: Problem with getHeader("Referer")
Hello all,
I have a problem getting the "Referer" header from the request object in a
JSP. The
only value I get for it is null. I printed a list of the available headers (via
getHeaderNames()) and this is the list I got:
User-Agent
Cookie
Accept
Host
Accept-Encoding
Accept-Language
Connection
Does anyone have an idea why I can't get "Referer"?
Sincerely,
Dan

Re: Problem with getHeader(Referer)
I've tried it with IE 5.5, Netscape 4.7, and Netscape 6. All 3 give the same result (null). Any other ideas? Is there any kind of config option in tomcat that would effect this?

Re: Problem with getHeader(Referer)
If they're not large, I'd like to see what the code is (sending and receiving
pages.) If they're big, don't clutter the group but send 'em my way.

RE: Problem with getHeader(Referer)
Are you linking to the page or typing it in. There is no referer if you
type it in;
I use: request.getHeader(referer) (Note that referer is all lowercase)
and get the referer fine in tomcat 3.2.1
Good luck,
Craig
