hrefs in documents and sendRedirect()

[Russell Freeman <Ru...@sagemaker.com>]

To restate a so far unresolved problem,

Do I need to include the name of my context in all hyperlinks, e.g. if my
context is /foo, then a link will be <a href="/foo/index.html">, my
stylesheet will be in "/foo/styles.css" etc. 

So far things only work if I add the context prefix but not for
sendRedirect(), which seems to not need it? 

Confused,
Russ

If you are creating hyperlinks that start with "/" then you *do* need the
context path added on the front.  This is because the browser will interpret
such a URL as being relative to the server's document root.

If you use relative URLs, though (not starting with "/"), then you do *not* want
to add the context path.  For example, if you have a page "index.html" that
wants to create a link to a page "display.html" in the same directory, simply
write:

    <a href="display.html">The Display Page</a>

response.sendRedirect() converts relative URLs back to absolute ones (adding the
content path for you).  This behavior is required by the servlet specification,
although not every servlet container actually does it.

Russell,

In order to use

response.sendRedirect("/somepage.html");

you need to be working in the root context. Out of the box, this means
document path webapps/Root/somepage.html
(at least for tomcat 3.1).

If you make your own context, you will need /contextname/somepage.html,
which will translate to webapps/contextname/somepage.html. All of that stuff
is configurable. Please study server.xml to figure
out how.


Good luck,

Dave
