Response.SendRedirect problems
Hello all,
I have a problem for my application and this prob is causing an entire netw=
ork of users from using my application. I will appreciate
if you guys can help me solve my prob.
It concerns the servlet response.sendRedirect(...) method.
When using the response.sendRedirect("/myexample") in my java class, i do n=
ot want the servlet engine to reconstruct
an absolute URL, before sending the response to the browser. I want it to b=
e handle by the browser keeping it relative throughout
the application. I know it's possible, but i dunno how to do it. Can you he=
lp ?=20
The URL reconstruction by the servlet engine during a redirection is causin=
g some problems in my application.
Example:
I have this link on browser http://127.0.0.1:<port_number>, when performing=
a sendRedirect, i'm losing the <port_number>
during the url reconstruction by the servlet engine.
On the other hand, i have another application that is interconnected, but i=
n this application, the url is relative throughout, even though
it passes through the response.sendRedirect(...) and consequently, i do not=
have this prob in this application.
Im using tomcat-4.1 and i'm checking the URL redirection using the HTTP liv=
e header plugins for firefox.
Thank you for your help.
Regards,
Ashwin

If you use sendRedirect, it's not possible:
sendRedirect
public void *sendRedirect*(java.lang.String location)
throws java.io.IOException
Sends a temporary redirect response to the client using the specified
redirect location URL. This method can accept relative URLs; the servlet
container _must convert the relative URL to an absolute URL before
sending the response to the client_. If the location is relative without
a leading '/' the container interprets it as relative to the current
request URI. If the location is relative with a leading '/' the
container interprets it as relative to the servlet container root.

It shouldn't unless either application or tomcat has bugs. :)

That's probably because tomcat is not aware, for various reason, of the
correct port number (behind a proxy or apache for example). You can
specify in tomcat configuration which port number to use when
reconstructing urls:
http://tomcat.apache.org/tomcat-4.1-doc/config/http11.html (see
'redirectPort')

If it's relative, it's not using sendRedirect , but it's setting by
itself the response header (response.addHeader() )

Maybe try to upgrade? ;)

It's probably not possible using response.sendRedirect, but it should be
possible using response.setStatus(302) (or whatever response code you
want) and response.setHeader("Location", "/myexample").
Note that this violates the HTTP spec
(http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.30) which
says that the Location response header is fully-qualified.

Faheem, you can't have a relative "Location" that includes a port
number: that will require an absolute (fully-qualified) URI. If Tomcat
is incorrectly (or not at all) inserting the port number into the
Location field, please let me know.

That is not possible, because of how HTTP spec is written.

You should describe your configuration in detail first. Though I
think you miss "proxyPort" attribute on a connector. (IIRC, it should
not be necessary for AJP though).

Hi Ashwin
I am too facing the same issue now , On redirection the port number is
getting omitted, Since this is a 2 years back thread, I suppose you might
have got the solution, Please reply back with the solution.
thanks

This request violates the servlet specification. From the 2.4 spec:
"SRV.5.3 Convenience Methods
The following convenience methods exist in the HttpServletResponse
interface:
• sendRedirect
• sendError
The sendRedirect method will set the appropriate headers and content
body to redirect the client to a different URL. It is legal to call this
method with a relative URL path, however the underlying container must
translate the relative path to a fully qualified URL for transmission
back to the client. If a partial URL is given and, for whatever reason,
cannot be converted into a valid URL, then this method must throw an
IllegalArgumentException.
"

Why do you care? The browser needs an absolute URL to contact the
server, anyway, so it shouldn't matter.
Let me guess... you want to use URLs like "../somewhere/else" all over
the place. This is a management headache. It's much better to root
everything in "contextPath + relativeURL", especially because that's how
/everybody/ does it, and it's compatible with the servlet specification.

Really? Can you post a servlet or JSP that fails in this way?
