302 Redirect Problem

I'm running Sun Java Web Server 6.0. I've got multiple virtual web servers mapped to different ports on one server. I'd like to enable users to type something like:
http://www.mysite.com/training
but if they leave off the trailing slash a 302 redirect error will occur. I read in an earlier post on this site that if you put servername="mysite:8088" in the server.xml file this will solve the problem . I have tried this but still get 302 errors.
Any ideas? Thanks.

If your load balancer is forwarding requests from one port to another, it should also rewrite the port number in Location header fields returned from Web Server. You can check your load balancer's documentation for details on how to configure your load balanacer.
If for some reason it's not possible to correctly configure your load balancer, you can override the port number Web Server will use in redirects by editing the servername attribute in server.xml. In your case, you would specify servername="www.mysite.com:80".

FF 13.0.1 - Constant 301, 302 redirects and pages not loading up... Has anyone encountered the same issue? I hate having to go back using IE

That i log in my Gmail, Hotmail, Facebook and the CMS of my Joomla 1.5 website, i keep on getting issues such as 301 or 302 redirects...
When i went to input.mozilla.org/feedback , the page showed completely blank....
I hate having to use IE as my second browser...

Hi,
Are the sites working in IE?? You can consider the [https://support.mozilla.org/en-US/kb/reset-firefox-easily-fix-most-problems Reset Firefox] feature via '''Help''' ('''Alt''' + '''H''') > '''Troubleshooting Information'''.

Why the initial 302 redirect?

I've been knocking around this problem with BEA for awhile now, with no
          resolution yet. Why does the initial request to my site first get a 302
          redirect page that then leads to the actual page I wanted served
          (index.jsp)? I don't have it configured to do any redirect, and the BEA
          engineers have told me that this is simply the way weblogic and other
          appservers are designed. DO most of the other appserver do this? Why can't
          it just be made to return the requested page right up front? They (the BEA
          engineers) claim that weblogic cannot be configured to do this.
          Oh, and the reason I ask is that we've been advised of problems with
          crawlers not following these redirect pages. Don't know if I believe that
          or not.


Hi himanshu1979,
<jsp:farward> is compulsary
String destination;
/* construct your destination url as you like */
this.getServletContext().getRequestDispatcher(destination).forward(request,
response);
Browser is showing ur jsp from the cache.
So you can instruct the browser not to do that by using
<code>
response.setHeader("Expires","0");
</code>
or
<code>
response.setHeader("Pragme","no-cache");
</code>

302 Redirect Location Header Rewrite not working with code upgrade

Hi,
Description:
We have a portal webservice hosted by an ACE4710. It has two services (www/https) on the same IP 10.1.1.1.
One is a redirect service that redirects all requests to tcp/80 on this ip to the other which is a 'standard' https proxy service.
The backend servers are http only. Externally everything needs to be https.
So we have an ssl proxy and Location header http to https rewrite on the https service.
The configuration below operates correctly on v5_1_2.
But with a code upgrade to 5_3_1b, the Location header rewrite does not work.
We've tried several different configurations and even 'ssl url location rewrite ".*". It just looks like the ACE is completely ignoring the configuration to rewrite the Location field.
Reverting to the older code fixes the problem.
Problem seen:
Here is the problem as seen on the *client*. The 302 redirect Location header is NOT rewritten:
Response headers:
HTTP/1.1 302 FOUND
Server: nginx
Date: Fri, 20 Mar 2015 10:59:43 GMT
Content-Type: text/html; charset=utf-8
Content-Length: 295
Connection: keep-alive

X-Frame-Options: DENY
HTTPSampleResult fields:
ContentType: text/html; charset=utf-8
DataEncoding: utf-8
Config extract:
1) Set up the servers (4 normal on tcp/80 and one for a redirect)
rserver host WEBSERVICE-1
ip address 192.168.1.1
conn-limit max 200000 min 160000
inservice
...and the same for the other three
rserver redirect PORTAL_REDIRECT
webhost-redirection https://%h/%p 302
inservice
2) Set up the server farms
serverfarm host PORTAL_LIVE
probe webping
rserver WEBSERVICE-1 80
    inservice
rserver WEBSERVICE-2 80
    inservice
rserver WEBSERVICE-3 80
    inservice
rserver WEBSERVICE-4 80
    inservice
serverfarm redirect PORTAL_HTTP_REDIRECT
rserver PORTAL_REDIRECT
    inservice
3) Setup the ssl proxy and a location rewrite to https for responses from the servers
action-list type modify http HTTPS_LOCATION
header rewrite response Location header-value "http://(.*)" replace "https://%1"
ssl-proxy service WEB_SSL_PROXY
key webportal.key
cert webportal.crt
chaingroup root-chain
ssl advanced-options SSL-SECURE-STRONG-WEB
4) Set up the L4 services
class-map match-all PORTAL_HTTP
2 match virtual-address 10.1.1.1 tcp eq www
class-map match-all PORTAL_SSL
2 match virtual-address 10.1.1.1 tcp eq https
5) Setup the policy maps - one for the reals servers with header rewrite for redirects
policy-map type loadbalance http first-match PORTAL_HTTP
class class-default
    serverfarm PORTAL_HTTP_REDIRECT
policy-map type loadbalance http first-match PORTAL_SSL
class class-default
    serverfarm PORTAL_LIVE
    action HTTPS_LOCATION
6) Create the service policy
policy-map multi-match EXTERNAL-SERVICES
class PORTAL_SSL
    loadbalance vip inservice
    loadbalance policy PORTAL_SSL
    loadbalance vip icmp-reply
    appl-parameter http advanced-options PARAM-HTTP
    ssl-proxy server WEB_SSL_PROXY
class PORTAL_HTTP
    loadbalance vip inservice
    loadbalance policy PORTAL_HTTP
    loadbalance vip icmp-reply
7) Apply to the interface
interface vlan 211
description External Access

peer ip address x.x.x.x 255.255.255.0
access-group input PERMIT-ALL

no shutdown

I found that the v5_3_1b code seems to need a bit of extra configuration and it now works ok.

Keeping query strings despite an automatic 302 redirect

is there anyway for a query string to persist despite an automatic 302 redirect by the server??
for instance if my site has a 'tmp' directory and i want to pass a parameter to the index page in 'tmp'
... but I go to
http://www.mysite.com/tmp?qvar=something
in a browser, the server will automatically do a 302 redirect to
http://www.mysite.com/tmp/
so the query string variable is lost.
i thought about having a filter run, to pick off the query string variable before the redirect, but the filter will only run after the redirect happens.
any insight would be great.
thanks.

: invalid content type for SOAP: TEXT/HTML; HTTP 302 Redirect

Hi Experts,
I am facing with the flowing error when we are receiving for the soap receiver chanel.
Message processing failed. Cause: com.sap.engine.interfaces.messaging.api.exception.MessagingException: java.io.IOException: invalid content type for SOAP: TEXT/HTML; HTTP 302 Redirect
is their any content type to give in soap receiver channel.
please let me know.
Regards
Raju

I think the message is misleading. HTTP 302 meaning is that the url specified in not found or invalid for that service. You might want to check with external system that the specified URL in the SOAP receiver communication channel is right? Also you can find the URL from the WSDL itself. Similar test do it outside PI using the SOAPUI or XMLSPY and see the response error.

Configure BI 302 redirect without trailing slash.

We have BI installed on a Windows server behind an F5 BigIP LTM. The LTM is handling the SSL communications to the BI pool. When going to https://bi.domain.com/xmlpserver/ everything is fine. Without the trailing slash it is throwing a 302 redirect to a non-ssl location:
$ curl -I -k https://bi.domain.com/xmlpserver
HTTP/1.1 302 Moved Temporarily
Server: Apache-Coyote/1.1
Location: http://bi.domain.com/xmlpserver/
Transfer-Encoding: chunked
Date: Fri, 01 Oct 2010 00:34:21 GMT
How can we change the redirect location to reflect the correct URL of: https://bi.domain.com/xmlpserver/?
Thanks in advance,
John

Using the af:image tag generates a http 302 redirect - image not cached

Using jdev 11.1.1.3.0 - I have a page template that displays a logo on top with the af:image tag. On my browser I have installed a sniffer called HttpWatch. When I look at the http requests I see that the image is never cached. Instead it shows a http return code of 302 (redirect) for the request fetching the image. the h:graphicImage tag does not have this behavior. Is this by design?

Hi,
don't know the code detail of h:graphicImage, but the ADF Faces image component reads the image from the resource loader (which is a servlet), which is not the same as just referencing the file on the public directory of the deployed application. So I assume that this is the reason why the image is not cached.

Dynamic form "Cancel" redirect problem in frames - bugfix?

My question: Is there a "long run" down side to my implementing this modification to style.js?
The below post by Ionut:MX Division Support Specialist worked for me as a solution to a current form "click cancel" redirect navigation problem:
When a DWtoolbox dynamic form wizard form is placed on a page within frames, clinking on cancel does not return a user to the list that sent them to the form. The user is sent somewhere else.
Begin Ionut post-------------
If you don't need to add extra parameters to the "Edit" button, you can solve the redirect problem by editing the "/includes/skins/style.js" file and replace:
nxt_list_edit_link_form(this, myinput.previousSibling.href);
with:
nxt_list_edit_link_form(this, a.href);
End----------------------
Thanks Ionut for the tip and anyone in support for letting me know if this is a safe mod for the long run,

Proxy redirect problem

I'm having a redirect problem going through a weblogic proxy. An app I was using appears to be redirecting the browser always to localhost:7121 which won't work with access via the my domain.
To explain fully I set up a test JSP page which outputs request.getRequestURL().toString() so I could trace what was happening. The weblogic configuration is explained below:
I'm using Weblogic 8.1 sp5. I've setup a 4 instances: a proxy (port 7120), redirector (port 7121) and cluster (two instances running on 7131, 7132)
If I navigate to:
http://localhost:7120/myapp/test.jsp my test page outputs: request.getRequestURL().toString() : http://localhost:7121/myapp/test.jsp
and again to:
http://localhost:7131/myapp/test.jsp my test page outputs: request.getRequestURL().toString() : http://localhost:7121/myapp/test.jsp
or
http://localhost:7132/myapp/test.jsp my test page outputs: request.getRequestURL().toString() : http://localhost:7121/myapp/test.jsp
The output is always the same ... it always says the requestURL is from localhost:7121 the redirector?
Can anyone help explain why I always get the same output? It is completely baffling me.
Thanks,
Matt

The problem was caused by incorrect configuration of FrontEndHttpPort and FrontEndListener and FrontEndHost in the cluster configuration. These values were incorrectly during config wizard install.

302 Redirect Error

I am getting a 302 redirect message when I send a HTTP POST command to a server. I can access the url directly and login just fine. Is it possible that I am getting a 302 due to either authentication or encoding issue? I am using basic authentication in the header and the content-type is form-urlencoded.

I can access the url directlyWhat does "directly" mean? If it means it works in your browser, that's because browsers take care of redirects for you.
Or does it mean something else?

B2C web shop - change/remove the 302 redirects for google search

Hi All,
We are making our webshop (http://hamperking.com.au) search engine friendly and implimenting a number of SEO recommendations. One of these recommendation requires the removal of the "works as designed" 302 redirects (temporary) in our CRM 2007 shop. Or atleast change them to 301 redirects (permenant). As the 302 redirects are temporary, google will not give them priority.
Can anyone point me into the right direction as to the SC and DC where is config is made?
Cheers,
Vic

I can not answer your direct question, but am curious as to why you are not using the [Web Crawler|https://service.sap.com/sap/support/notes/1128832] to accomplish this or perhaps you were unaware of it?

ACE: SSL termination, Probe and Redirect problem

Hello,
I have problem with three things: -1) SSL offload, -2) probe, and -3) server redirect.
1) I made SSL offload like shows attached file with "show run". But during going to the VIP address by the browser: https://192.168.254.143 I get window with Java error: java.lang.NullPointerException - I have to click OK on this window and then can work fine. Without SSL offload I don't have this error message in window.
When I have SSL offload I have following configuration:
ssl-proxy service SSL
key klucz.pem
cert certyfikat.pem
serverfarm host SFARM
rserver S1 8080
rserver S2 8080
policy-map multi-match SLB-POLICY
class SLB
ssl-proxy server SSL
Without SSL offloading I have only this:
serverfarm host SFARM
rserver S1 (without 8080!)
rserver S2
2) Right now I have two real servers and I send traffic to them by port TCP 8080. So I made probe to check TCP 8080 port availability.:
probe tcp TCP_8080
port 8080
interval 15
passdetect interval 60
serverfarm host SFARM
rserver S1 8080
probe TCP_8080
inservice
rserver S2 8080
probe TCP_8080
inservice
I want also check port TCP 6400 availability, and I only one from port 8080 or 6400 don't work - make real server unavailable. So must work TCP port 8080 ang 6400 togethet to treat real server as operational.
So I want to make something like this:
probe tcp TEST
port 8080 and 6400 !?! - ofcourse It is impossible but I want to make config with this functionality.
How to do this?
3) I hant to make that when I write in browser https://bo.kw.coig.biz/ = https://192.168.254.143 I want to be redirected to one of real server on address: https://bo.kw.coig.biz/businessobjects/enterprise115/desktoplaunch/InfoView/logon/logon.do
I made something like this:
rserver redirect S3
webhost-redirection https://%h/businessobjects/enterprise115/desktoplaunch/InfoView/logon/logon.do 302
inservice
serverfarm redirect REDIRECT
rserver S3
inservice
policy-map type loadbalance first-match POLICY-TYPE
class class-default
serverfarm REDIRECT
But this configuration dosn't work. I have in browser window with error messeging.
How to do this?

1/ this is a java problem.
Java is telling you that it attempted to use a null pointer. You need to check with the people who created the java program
2/ you can configure multiple tcp probe, one for each port you need to monitor and assign all the probes to the serverfarm.
BTW, you can assign the problem to the entire serverfarm so you don't need to specify it for each rserver.
3/ the problem with your redirect is that you applied to class-default.
So even a request to ...../logon will be redirected to ...../logon.
Therefore you just created a nice loop.
You need to create a class-map to only match the url "/" so the redirect is only applied then.

Crystal Report in an iFrame redirect problem

Hi!
I have built a page with a only Crystal Report on it, which I display in an iFrame on another page.
I have a hyperlink on the page that is used to redirect the iFrame by assigning the iFrame a name and setting the target of the hyperlink to the iFrame. When the user clicks the hyperlink, it will redirect the iFrame.
This all works fine up until the point at which you generate the actual Crystal report. After the report has generated, attempting to redirect the iFrame via the hyperlink causes a new browser tab/window to open. A few tests that I have run using Javascript or codebehind circumvent this issue, but as it stands I cannot use this method.
This issue has only just arisen with the VS2010 version of Crystal Reports. The older versions do not have this problem.
Research I have done into the issue have been fruitless and have tinkered with the Report Viewer itself a bit to no avail.
Is there an explanation for this issue and/or a means of getting past this?
Any help or nudge in a new direction is very much appreciated!
Regards,
Frank.

Hello Frank:
This issue has been reported to R&D for a fix (ADAPT01554950). At this time, the fix is targeted (not guaranteed) for Service Pack 3. ETA; mid 2012.
