Sun Web server 6.1 SP9 Reverse proxy - Changing Web Server Context

I am trying to configure a Reverse Proxy such that it can change the context of the requested URL.
My SOWS reverse proxy plug-in is running on server server1.sample.com and the destination server is running on server2.sample.com. The use case, the incoming URL is [|http://server1.sample.com/dummy1/]...... and I need to map this to {color:#0000ff}http://server2.sample.com/*dummy2*/.....;{color} It looks like the reverse proxy only maps to a server level but disregards the context. The reason I say that, in the server 2 logs I see - .... trying to GET /dummy1....; I needed the call to look for dummy2 context. Can this be done?

well, web server uri processing does not understand web application level context (in terms of java web applications). however, if you would like to map all uri's ending with /dummy1 to go to /dummy2, then you can easily do this with web server 7 regular express processing
http://blogs.sun.com/elving/entry/mass_virtual_hosting_in_7
http://docs.sun.com/app/docs/doc/820-6599/gdaer?a=view
besides web server 7 includes a very tightly integrated reverse proxy unlike 6.1 where you need reverse proxy as a separate plugin. so, you might want to check out if ws7 can serve your needs

Example of a successful reverse proxy to APEX using Apache and Oracle HTTP

If this helps anyone, I was able to set up a reverse proxy to APEX with Apache running on the reverse proxy server and Oracle HTTP server and APEX 3.2 on the APEX hosting server. I want to post this due to there is no
documentation on this that I can find. Oracle Metalink could not produce any "How To" document either.
On the reverse proxy server in the httpd.conf file:
ProxyRequests Off
SetEnv force-proxy-request-1.0.1
SetEnv proxy-nokeepalive 1
ProxyPassReverse /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPass /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPassReverse /i/ http://apex_server:8080/i/
ProxyPass /i/ http://apex_server:8080/i/
AddType text/xml .xbl
AddType text/x-component .htc
OR
ProxyRequests off
RewriteEngine On
RewriteRule ^/pls/apex/(.*)$ http://apex_server:8080/pls/apex/$1 [P,NE]
ProxyRequests off
ProxyPassReverse /i/ http://apex_server:8080/i/
RewriteEngine On
RewriteRule ^/i/(.*)$ http://apex_server:8080/i/$1 [P,NE]
And in the Oracle HTTP server httpd.conf file of the APEX hosting server:
NameVirtualHost 999.99.99.9:8080
<VirtualHost 999.99.99.9:8080>

Save session between two virtual directories in Reverse Proxy

All,
I'm having an issue and I'm hoping someone here can help me. I currently have an reverse proxy rule for say
/abc pointing to 10.10.10.10
We had to add to another virtual directory
/xyz pointing to 10.10.10.20
This is because of the limitation of the application where different parts are to be installed on different servers. What we are trying to achieve is to see if there is a way we can keep a session alive while the user is switching from /abc to /xyz.
We are using SJWS 7.0. Any help will be greatly appreciated.

How do I use Sun Web Server 7.0u1 reverse proxy to change public URLs?

Some of our installations use the Sun Web Server 7.0 (update 1, usually)
for hosting some of the public resource and reverse-proxying other parts
of the URI namespace from other backend servers (content, application
and other types of servers).
So far every type of backend server served a unique part of the namespace
and there was no collision of names, and the backend resources were
published in a one-to-one manner. That is, a backend resource like, say,
http://appserver:8080/content/page.html would be published in the internet
as http://www.publicsite.com/content/page.html
I was recently asked to research whether we can rename some parts of
the public URI namespace, to publish some or all resources as, say,
http://www.publicsite.com/data/page.html while using the same backend
resources.
Another quest, possibly related in solution, was to make a tidy url for the
first page the user opens of the site. That is, in the current solution when
a visitor types the url "www.publicsite.com" in his or her browser, our web
server returns an HTTP-302 redirect to the actual first page URL, so the
browser sends a second request (and changes the URL in its location bar).
One customer said that it is not "tidy". They don't want the URL to change
right upon first rendering the page. They want the root page to be rendered
instantly i the first HTTP request.
So far I found that I can't solve these problems. I believe these problems
share a solution because it relies on ability to control the actual URI strings
requested by Sun Web Server from backend servers.
Some details follow, now:
It seems that the reverse proxy (Service fn="service-passthrough") takes
only the $uri value which was originally requested by the browser. I didn't
yet manage to override this value while processing a request, not even if
I "restart" a request. Turning the error log up to "finest" I see that even
when making the "service-passthrough" operation, the Sun Web Server
still remembers that the request was for "/test" (in my test case below);
it does indeed ask the backend server for an URI "/test" and that fails.

in some version of Sun Web Server 7.0 or its opensourced siblings) ;)

Some of our installations use the Sun Web Server 7.0 (update 1, usually)please plan on installing the latest service pack - 7.0 Update 4. these updates addresses potentially critical bug fixes.
I was recently asked to research whether we can rename some parts of
the public URI namespace, to publish some or all resources as, say,
http://www.publicsite.com/data/page.html while using the same backend
resources.> now, if all the resources are under say /data, then how will you know which pages need to be sent to which back end resources. i guess, you probably meant to check for /data/page.html should go to <back-end>/content/page.html
yes, you could do something like
- edit your corresponding obj.conf (<hostname>-obj.conf or obj.conf depending on your configuration)
<Object name=¨default¨>
<If $uri = ¨/page/¨>
#move this nametrans SAF (for map directive - which is for reverse proxy within <if> clause)
NameTrans.. fn=map
</If
</Object>
and you could do https-<hostname>/bin/reconfig (dynamic reconfiguration) to check out if this is what you wanted. also, you might want to move config/server.xml <log-level> to finest and do your configuration . this way, you would get enough information on what is going on within your server logs.
finally,when you are satisfied, you might have to run the following command to make your manual change into admin config repository.
<install-root>/bin/wadm pull-config user=admin config=<hostname> <hostname>
<install-root>/bin/wadm deploy-config --user=admin <hostname>
you might want to check out this for more info on how you could use <if> else condition to handle your requirement.
http://docs.sun.com/app/docs/doc/820-6599/gdaer?a=view
finally, you might want to refer to this doc - which explains on ws7 request processing overview. this should provide you with some pointers as to what these different directives mean
http://docs.sun.com/app/docs/doc/820-6599/gbysz?a=view
>
One customer said that it is not "tidy". They don't want the URL to change

please check out the rewrite / restart SAF. this should help you.
http://docs.sun.com/app/docs/doc/820-6599/gdada?a=view
pl. understand that - like with more web servers - ordering of directives is very important within obj.conf. so, you might want to make sure that you verify the obj.conf directive ordering is what you want it to do..
It seems that the reverse proxy (Service fn="service-passthrough") takes

now, you are in the totally wrong direction. web server 7 includes a highly integrated reverse proxy solution compared to 6.1. unlike 6.1, you don´t have to download a separate plugin . however, you will need to manually migrate your 6.1 based reverse proxy settings into 7.0. please check out this blog link on how to set up a reverse proxy
http://blogs.sun.com/amit/entry/setting_up_a_reverse_proxy
feel free to post to us if you need any futher help
you are probably better off - starting fresh
- install ws7u4
- use gui or CLI to create a reverse proxy and map one on one - say content
http://docs.sun.com/app/docs/doc/820-6601/create-reverse-proxy-1?a=view
if you don´t plan on using ws7 integrated web container (ability to process jsp/servlet), then you could disable java support as well. this should reduce your server memory footprint
<install-root>/bin/wadm disable-java user=admin config=<hostname>
<install-root>/bin/wadm create-reverse-proxy user=admin uri-prefix=/content server=<http://your back end server/ config=<hostname> --vs=<hostname>
<install-root>/bin/wadm deploy-config --user=admin <hostname>
now, you can check out the regular express processing and <if> syntax from our docs and try it out within <https-<hostname>/config/<hostname>-obj.conf> file and restart the server. pl. note that once you disable java, ws7 admin server creates <vs>-obj.conf and you need to edit this file and not default obj.conf for your changes to be read by server.
>
I have also tried "restart"ing the request like this:
NameTrans fn="restart" uri="/data"
ordering is very important here... you need to do this some thing like
<Object name=default>
<If not $restarted>
NameTrans fn=restart uri from=/¨ uri=/foo.
</If>

Reverse Proxy with Sun Web Server 7 update 4

Hi All,
I've just migrating to Sun Java System Web Server 7.0U4 B12/02/2008 from Sun Java System Web Server 7.0-Technology-Preview-3 B09/13/2006. I've have the two web servers running side by side on separate machines. Both have a VS configured as a reverse proxy pointing to the same apache tomcat web server.
The Tech Preview 3 server works fine and has been doing since it was installed. However the Update 4 server doesn't. I can access the tomcat app via the U4 server in a browser, but not with the app on my mobile (sync ML). Snooping the traffic show me that the U4 server is sending a different response that the Tech Preview server. I'm thinking it may have to do with Transfer Encoding: chunked. I've looked around the web to see if I can turn this off in the U4 server, as I seem to recall having to do so at some point in my life, though I can't remember when and with what.
Does anybody have any clues they can throw at me?? Or anybody know what has change in the reverse proxy part of the web server from Tech Preview 3 to U4??
Both VS reverse proxies are congfigured exactly the same.
Thanks,
Stuart.

well, technology preview is what the name says .. i am surprised that u decided to stick with a technology preview release all these days.. in any case, there should not have any feature change between technology preview build and U4. but , there has been lot of bug fixes - so, unless we know the exact problem - we can't easily narrow down the change between tp3 build with U4 and find out how it is affecting u.
here is a related article on how to use chunked encoding within web server 7
http://developers.sun.com/webtier/reference/techart/chunked_req.html
now, to help you more appropriately, you need to provide us with errors (probably with log level set to finest within server.xml) and let us know with the error reported by web server when it is unable to send those requests to back end tomcat
you can set log level to finest by running the following command
/sun/webserver7/bin/wadm set-config-prop -user=admin --config=<hostname> log-level=finest
/sun/webserver7/bin/wadm deploy-config --user=admin <hostname>
http://docs.sun.com/app/docs/doc/820-4842/set-config-prop-1?a=view
(once you have identified the problem, you might want to set log level to info as setting to finest will cause your logs to grow humongous and also hurt performance

Sun Web server 7 - Reverse proxy to different

Hi All,
I have following scenario:
I have deploy my application into 2 dedicated weblogic servers, http://host1:7001/myapp and http://host2:7001/myapp. How can I configure the reverse proxy so whenever user enter the URL, webserver will forward different app server like below;
#1 - http://abc.com >> web server will forward to http://host1:7001/myapp
#2 - http://abc.com/controller>> web server will forward to http://host2:7001/myapp
I follow tutorial from this link >> http://blogs.sun.com/amit/entry/setting_up_a_reverse_proxy
For requirement #1 it work perfectly since i put URI = /myapp and Server URL = http://host1:7001.
But for #2, it doesnt work since I put the URI=/controller.
We wanted to be like http://abc.com/controller, so it will forward to second app server which difference application.
Is it possible? or any other to do like that?
Thanks!

Hi Sriram,
I'm having similar problem with atehac, the only difference is that the web server
#1 http://domain.com/web1 >> forwarded to http://local-pc1.com:8080/
#2 http://domain.com/web2 >> forwarded to http://local-pc2.com:8080/
This is the setting that I've made in <vs>obj.conf :
NameTrans fn="map" from="/web1" name="reverse-proxy-/web1" to="http:/"
NameTrans fn="map" from="/" name="reverse-proxy-/web1" to="http:/"
NameTrans fn="map" from="/web2" name="reverse-proxy-/web2" to="http:/"
NameTrans fn="map" from="/" name="reverse-proxy-/web2" to="http:/"
<Object name="reverse-proxy-/web1">
Route fn="set-origin-server" server="http://local-pc1.com:8080"
</Object>
<Object name="reverse-proxy-/web2">
Route fn="set-origin-server" server="http://local-pc2.com:8080"
</Object>
But the problem is local-pc2 won't be able to be accessed, while for local-pc1 will be mapped, but it omit /web1
So it will be like http://domain.com/web1 at the beginning, but after I press enter it became like http://domain.com
What I wish is something like http://domain.com/web1 all the way.
Do you have any idea Sriram?
Regards,
Berry

Sun Web Server Reverse Proxy and Weblogic HTTP to HTTPS redirection

Hi,
I am currently testing reverse-proxy from SJSW 7.0 update 5 to Weblogic server but I have encountered an issue.
I have configured a context root to be forwarded to weblogic:
Web Server: www.server.com
URI: /path
Reverse Proxy URL: wlserver:9000
When I access https://www.server.com/path, I am getting the correct page. The issue is, the weblogic server is configured to redirect HTTP access to HTTPS, i.e., when I access http://www.server.com/path, it should be redirected to https://www.server.com/path. However, that is not the case. What happens is that I am being redirected instead to https://www.server.com/.
If I don't use reverse proxy, that is, if I use the libproxy.so from weblogic, I get the correct redirection.
Would appreciate it very much if someone can help me troubleshoot this issue.
Thanks in advance!

I am not sure, how you have configured your reverse proxy since you didn't attach / refer your current configuration file. this is how I would do it..
- create a new configuration (using web server 7 admin gui , within configuration wizard, disable java option if you plan to use web server 7 only for reverse proxy)
- select this new configuration and go to reverse proxy and try to reverse proxy / to the origin server.
that is all it should need.
your obj.conf or <hostname>-obj.conf depending on your configuration should look like following snippet
<Object name="default">
AuthTrans..
NameTrans fn=map from="/" to="/path" name="reverse-proxy-/"
</object>
<Object name="reverse-proxy-/">
Route fn=....
Service ..
</Object>
this is all you should need..
However, if you wanted to add complexity to your configuration, you could do some thing like
<Object name="default">
Auth..
<If defined $security>
NameTrans fn=map from="/" to="/path" name="reverse-proxy-/"
</If>
</Object>
<Object name="reverse-proxy-/">
Route...

Web Server 7 Reverse Proxy URI Config

I am testing WS 7.2 to replace WS 6.1 and need input on the configuration of the reverse proxy setup. We currently are using the reverse proxy plugin on our 6.1 servers but I cannot get the same configuration to work on 7.2. I have followed the admin document but I don't want to use / as my URI. I need to only proxy requests for URLs that end in *cfm. Can I configure the new server to work like the 6.1 version?
6.1 Config
=======
obj.conf
NameTrans fn="assign-name" from="(*.cfm)" name="passthrough"
<Object name="passthrough">
ObjectType fn="force-type" type="magnus-internal/passthrough"
Service type="magnus-internal/passthrough" fn="service-passthrough" servers="http://host:8281"

In Web Server 7.0 you can use built in reverse proxy feature rather than using libpassthrough.so

Sun One Application Server 7 SSL Reverse Proxy Setup?

Hi,
I've made a similiar post on the Web Server forum,
http://forum.sun.com/jive/thread.jspa?threadID=95666&tstart=0
I've noticed there's a reverse proxy plug in setup for Web Server,
as well as a AddOn package for Application Server.
I've so far successfully installed the reverse proxy plugin for
the Web Server and it manage to passthrough the jsp contents
to the Application Server.
There's a file in our application server, Step2Cert.jsp in the
appserver that requires to be viewed/accessed in https mode
and I'm guessing the Web Server to Application Server communication
should be in https?
Anywhere I can find references on how this can be done?

I've not installed the AddOn package for the Appserver yet. But
I figured I should, right? I'm rather confused about the two

Oracle Java Web Server 6.1 / 7.0 Reverse Proxy

Hello everyone,
I have just installed both Sun Java Web Server versions 6.1 and 7.0 on Windows x86, trying to configure the Reverse Proxy Plugin, but none of the installations came with the libpassthrough.dll file mentioned in several documentations.
I have searched both Google and Oracle websites but links on Google point to the former sun.com website and Oracle gives nothing :(
update: I've installed Oracle iPlanet Web Server 7.0.15 and got only digest, fastcgi, htaccess and loadbal in the plugins folder, no libpassthrough :( Help!
Does anybody know where can i get the Reverse Proxy Plugin for Windows ?
Thank you very much,
Daniel.
Edited by: user2579623 on 07/08/2012 13:19

In 6.1, the libpassthrough library comes in a separate download, usually with the application server, ie glassfish. In 7.x it is build in so there is no separate library to add, the functionality is just there and can even be configured from the web admin interface. Just use web server 7 and have a look at the admin console.

Problem on Setting up a Reverse Proxy on Web Proxy Server 4.0.1

After you setup a reverse proxy using Web Proxy Server 4.0.1, if you get the following error --
Proxy denies fulfilling the request
Your client is not allowed to access the requested object.You probably forget to add a regular mapping from: / to: http://http.site.com/. The information provided in 4.0.1 Administration guide is misleading. You will have to add it NOW manually. (Note: in 3.6 it will be added automaticly)
You will have to do the following step manually, what provided in the manual is misleading --
Sun Java� System Web Proxy Server 4 .0.1 Administration Guide 2005Q4
Chapter 14 Using a Reverse Proxy
"Setting up a Reverse Proxy"
5. To make the change, click OK.
Once you click the OK button, the proxy server adds one or more additional
mappings. To see the mappings, click the link called View/Edit Mappings.
Additional mappings would be in the following format:
from: /
to: http://http.site.com/

thanks, will verify and update the docs.

Automatically authenticate reverse proxy on ML web server

My Mini server is running 10.8.2. I've set apache up to reverse proxy several web cameras and I then force authentication to the domain via a group. However the cameras have their own authentication that I can't circumvent. Is there a way to authenticate to the cameras via apache's reverse proxy? Here is my current apache config....
ProxyRequests off
ProxyPass /camera1/ http://192.168.0.30/
ProxyPass /camera2/ http://192.168.0.32/
ProxyPass /camera3/ http://192.168.0.34/
ProxyPass /camera4/ http://192.168.0.36/
ProxyPassReverse /camera1 http://192.168.0.30
ProxyPassReverse /camera2 http://192.168.0.32
ProxyPassReverse /camera3 http://192.168.0.34
ProxyPassReverse /camera4 http://192.168.0.36

well, technology preview is what the name says .. i am surprised that u decided to stick with a technology preview release all these days.. in any case, there should not have any feature change between technology preview build and U4. but , there has been lot of bug fixes - so, unless we know the exact problem - we can't easily narrow down the change between tp3 build with U4 and find out how it is affecting u.
here is a related article on how to use chunked encoding within web server 7
http://developers.sun.com/webtier/reference/techart/chunked_req.html
now, to help you more appropriately, you need to provide us with errors (probably with log level set to finest within server.xml) and let us know with the error reported by web server when it is unable to send those requests to back end tomcat
you can set log level to finest by running the following command
/sun/webserver7/bin/wadm set-config-prop -user=admin --config=<hostname> log-level=finest
/sun/webserver7/bin/wadm deploy-config --user=admin <hostname>
http://docs.sun.com/app/docs/doc/820-4842/set-config-prop-1?a=view
(once you have identified the problem, you might want to set log level to info as setting to finest will cause your logs to grow humongous and also hurt performance

Reverse Proxy installatio on Web Server

Hi,
Can anyone help me to install a reverse proxy on a Web Server and configure it. Is there any documentation and where and how I can download the reverse proxy for Web Server.
Thanks in Advance.

Reverse proxy functionality is inbuit in Sun Java System Web Server 7.0.
Official WS 7.0 docs are at :

WebServer 6.1 SP3 SSL reverse proxy to Sun One Application Server 7

I have an application in the appserver7 that requires SSL authentication. I have already installed a self cert in the appserver7, and the authentication works fine when I browse directly to the appserver.
The appserver7 has both listener for port 80 and 443 enabled.
I'm currently setting up a webserver (WebServer 6.1 SP3) to act as a reverse proxy to the appserver7. The reverse proxy for the basic jsp pages found in the appserver worked fine.
When I try to access the login page, in the appserver, in ssl mode, I am unable to do so. I then try changing the obj.conf to the following, from http to https:
<Object name="passthrough">
ObjectType fn="force-type" type="magnus-internal/passthrough"
Service fn="service-passthrough" method="(GET|HEAD|POST)" servers="https://172.2
8.48.53"
However, it still doesn't work.
Do I need to install a self cert in the webserver and enable the ssl listener as well?
Do I need to install any reverse proxy addon for the appserver? Any
setup for the obj.conf in the appserver?
Any ideas how to get this done?
Thanks.
Mac.

The Web Server 6.1 SP3 Reverse Proxy Plugin is supported, but it sounds like you're trying to do something that simply isn't possible.
If you want the Reverse Proxy Plugin to perform SSL mutual authentication with the Application Server using the client's certificate, that's impossible due to the nature of SSL mutual authentication. If the plugin could impersonate the client, then SSL would be vulnerable to MITM (Man In The Middle Attacks). Fortunately, SSL isn't vulnerable to such attacks because the plugin doesn't know the client's private key.
If you simply want the Reverse Proxy Plugin to pass information about the client's certificate along to the Application Server, that hapens automatically. There's nothing special to configure. Note that the plugin will not authenticate to the Application Server in this case. Rather, it will simply copy the X.509 certificate into the proprietary Proxy-auth-cert: HTTP request header.
The application running on the Application Server can inspect the Proxy-auth-cert: header using standard Servlet APIs. Alternatively, you can use Application Server 7's auth-passthrough AuthTrans SAF to cause the contents of the Proxy-auth-cert: header to be copied to the javax.servlet.request.X509Certificate Servlet attribute.

Problem: Protect Sun Web Proxy Server 4.0.5 with Policy Agent 2.2

We are trying to protect the Sun Web proxy Server 4.0.5 with policy agent 2.2 on solaris 10 machine.
We are using Access Manager 7.1 along with directory server 6.2
We are trying to protect the web proxy console url http://domain.example.com with that policy agent so that when we hit web proxy console url
it should through us access manager login page ie http://abc.com/amserver.
How can we achieve this.What all changes required in the AMAgent.properties file.Please suggest.

Hi subho,
problem is fixed. i have unistalled the policy agent and reinstalled it again. the problem i found is we didnt stop the webproxy instance when installing policy agent. Thanks for the reply
