Re: 301 Redirect Question

[Tim Funk]

You need to code them yourself in your servlet/jsp.
response.setStatus(HttpServletResponse.SC_MOVED_PERMANENTLY);
response.addHeader("Location", "/more/cowbell.jsp");

Subject: enormous loggin when starting tomcat
Hello
I'm using Tomcat 5.0.28 and I'm trying to deploy a struts application.
This application is rather large and so is my struts-config.xml file.
When tomcat starts or I restart the application, I have to
wait more than a minute (sometimes 4') before all the log
messages are done.
Does anyone have an idea what's the cause of this and how I
can resolve it ?
Thanks in advance
Koen

301 Redirect Question

[Lyndon Smith]

Hi Allistair

I have a question for the Tomcat User Group.

I hope you don't mind me asking you because the answer should be a simple
yes or no but I can't get an answer anywhere.

I am new to the mailing list and I don't know how to submit a question to
it.

The Question:

Is it possible with Tomcat 4.1.30 running within Apache Web Server to use
301 redirects?

(If so how?)

Regards

Lyndon

Re: Server.xml / App Context / Redirect question

Copy everything in your projectX web application to

SSL, JK redirect question

[Martin Jacobson]

I have tc4.1.12, Apache 2.0.43 mod_ssl and mod_jk set up and working 
successfully on my Mac (OS X 10.1.5), but tweaking the Apache config to 
get it to work was... involved, let's say :-)

Users enter the site (using http: protocol) at /drs/home. This contains 
a button labelled "Login" that takes them to /drs/private/home. Because 
/drs/private/* is under a security contraint, it triggers a redirect to 
/drs/login which POSTs to j_security_check, etc.

Previously, using tomcat-standalone, the 
CONFIDENTIAL triggered the 
switch to https: - however, this no longer works when Apache/mod_jk are 
in the loop.

Because /drs/private/* isn't accessible via http: I was getting an 
Apache-generated 404 error when the login button on the home page was 
clicked: the solution I found was to place a
Redirect /drs/private/home https:///drs/private/home
in httpd.conf

Of course, this gives an extra redirect, and seems inelegant...does 
anyone have a better solution? [And no, I don't think mod_rewrite is a 
better solution!]

Martin.

PS I don't want to hard-code the full URL in the button on-click 
handler, as I don't want to have Yet Another Thing To Change when I move 
to the production server.

RE: Redirect question

I don't know how the flow of your webapp is working in this
situation but if you put the following in the referrer to 
the first jsp or possibly on your first jsp and ACTION="redirect.jsp"
depending on you work flow:





...


The values will be in the request if you handle navigation
by submitting the form.

The only reason this would be programmatically better than the
previous solution is if it can not be assumed that the user
has cookies enabled or if cookies are not even an option per
project specs.

Unfortunately it's the browser which decides which frame to load a page
into, you can't force it on the server side. So a servlet or JSP page can't
decide to load itself into a particular frame any more than a plain HTML
page can decide to load _itself_ into a particular frame.

So if your sendRedirect("index.html") is in myServlet, the HTML which contains
the link tag that loads the original URL has to specify the frame to load 
it in:

click

Whatever output myServlet generates, even if it's a redirect, will show up in
the top frame.

A technique to get better control over your framesets is to load a frameset
which is a JSP page, and give it some parameter which will tell it what to
load in each frame. All of your links will contain target="_top", and the 
entire
frameset is loaded:

sendRedirect("smart_frameset.jsp?main=index.html&nav=nav.html");

Your smart_frameset.jsp checks its parameters and writes its frameset tags
accordingly to load the correct URL in each frame. It's not terribly efficient,
since you're reloading the whole frameset whether you need to or not.

Deep down, a JSP page is just a Java class.  And the Java language has no
concept like the setjmp()/longjmp() combination of C, where you can change the
logical flow of control with what amounts to a "go to" statement to a completely
different method in a completely different source file.

When you call response.sendRedirect() -- or RequestDispatcher.forward(), which
has the same basic issue -- control will ultimately be returned to your page
when the method you just called returns.  It is up to you to add a "return"
statement afterwards, to stop creating the remainder of the current page.

The only time that this is done for you by the container is when you use
, or execute a JSP custom tag that tells the container to skip the
remainder of the current page.

send redirect question

[Rick Bosch]

we have several jsp pages that call beans.  Some beans for one reason or
another will redirect a user to another page, howver in some cases its
possible for a redirect to occur and if the logic of the bean is to continue
writing after a reddirect the client get messed up pages usually the
original then some http headers and then the new page.  How is it jsp pages
are somehow "aware" of a redirect but if i call a redirect from a bean it
seems to be ignored???
