DMZ with reverse proxy

Hi All,
I am trying to configure DMZ.
But I am having only one node for apache.
So I thought of configuring DMZ using Reverse Proxy with no External node.
But I am bit confused with configuration of Reverse Proxy using the apache shipped with E-business
My current archecture like:
Node 1 : Apache ,Forms and MWA
Node 2 : CM and DB
OS : AIX 5.3
Version : 11.5.10.2
DB : 10.2.0.4
1.Will there be 2 apache process running as applmgr on node1(one for external and other for internal)
2.Will there be 2 context files in node1 (one for external and other for internale)
3.How to configure 2 Server name for node1
Thanks in advance

Hi,
Did you review (Note: 438744.1 - Case History: Implementing a Reverse Proxy Alone in a DMZ Configuration - 11i)?

Hussein

Fronting actual application with reverse proxy

Hi All
I am very novice to proxy server field.
Actually i have to use proxy server as a top layer for an application which is using Sun access manager authentication.
Now to configure the reverse proxy i first map the regular and reverse mapping for my application lets say mapping
http://rp1/app1 to http://example.com/app
Now this app http://example.com/app is protected by Sun Access manager and redirect the request to url something like http://hostname/amserver/UI/login/goto.....
Now when the user hit the url http://rp1/app1 as the application is protected it redirect the user to
http://hostname/amserver/UI/login/goto..... and it is visible to user which should not be.
I want that actual url shud not be shown to the user so i also try to map
http://hostname/amserver/UI/login with reverse proxy url (new).
but then it gives me HTTP 403 error.
I want to know in case of reverse proxy if the destination url redirect the request to some other application how can we avoid the user to show the actual redirection url and show him some proxy url so that user will not be know the url where actually the applications are deployed.
Please help.
Any pointer will be really helpful.
Thanks in advance.

Peoplesoft Portal with Reverse Proxy, content provider also need RP?

Hello there,
I need your help, I am currently implementing a PS Portal, I set my CRM as content provider, for safety reasons public access portal is configured using a reverse proxy (rp), my question is: Is there a different option to configure the CRM also with reverse proxy? as static content generated by CRM are then shown through the Website Portal (already rp),
Thanks and regards.
Alexander C.

I also would like overcome this issue. I could not find an answer anywhere on Metalink or OTN.
Can a reverse-proxy (i.e. using ProxyPass & Reverse) be used with and internal Portal?

Portal 10.1.2 with reverse proxy

Hi,
Does anybody configure Portal 10.1.2 working with reverse proxy behind the firewall?
I tried using generic docs and Metalink Notes 270160.1, 262451.1, unsuccessful.
I ended with SSO not starting at all.
Now i have fresh install without proxy and I am looking for some success reference.
Thanx
Jiri

What are you going to use for the Reverse Proxy?
1) Apache
2) Oracle Isapi IIS Plugin
3) Oracle HTTP Server
4) Webcache
I've been dealing with basically #1, #2 for the past month so I could have some info for you there. How is your MT's / Infra configured? same server, different servers? Will the proxy be in another server? Do you have webcache running?
I would suggest making sure it works internally first with the name that you want before putting the reverse proxy infront of it. I have 1 URL that works now both internally and externally though a reverse proxy.
It sounds like your having some SSO configuration related issues with your name. These are somewhat difficult to troubleshoot, so if needed open a TAR and Oracle Support can pretty quickly help you resolve those.

Portal 9041 with reverse proxy

Hi,
Does anybody configure Portal 9.0.4.1 working with reverse proxy ?
I doesn't find any doc for 9041... only for 10.1.2 and 902
Thao

The 9.0.4 Portal Configuration Guide has a section about setting this up:
5.6 Configuring Reverse Proxy Servers
The 9.0.4 documentation library can be found on OTN:
http://www.oracle.com/technology/documentation/appserver10g.html

Load Balancing with Reverse Proxy Plug-in in SunOne 6.1

Hello
we are configuring our reverse proxy web server SunOn 6.1 for load balancing and we have some conflicting information that we have found on the internet. The options we have found are the following:
1- In one case, it seems that all we need to do is add the destination servers to the servers parameter (quoted, space-delimited). We have read that the proxy server will simply round-robin requests.
2- In another case, we have seen that we have to use an loadbalancer.xml file with the server names and reference the file from both magnus.conf and obj.conf.
I have doubts about the second option because I really think this is configuration in 7.0 not 6.1.
Also, I also need to configure session stickiness but it is not clear how this works. There is an option for sticky cookies that defaults to JSESSIONID if not configured. Does this mean that I will have session stickiness but simply without the use of cookies?
ANY HELP? We need to solve this in the next day.

now we are one step further and receive a HTTP 401 on the reverse proxy. It looks like the client cert from HCI is not handled correctly. Can you help?

Windows Intergrated Authentication with reverse proxy issue with Safari

Hi All
I having a application which has Windows Integrated Authentication, for Internet users we are having a reverse proxy which has a IIS server which will authenticate using basic authentication then redirected to the actual application, every thing works as expected in IE and firefox but in safari there is a second login dialog box appears. When I did a packet capture using wireshark I noticed that in IE and FF the basic authentication which is carried forward to the actual application from IIS server but in Safari there is a NTLM negotiation in between because there is a 401 response so my application asks for on more login dialog. Dose any one knows why safari is behaving like this?
Thanks & Regards

I found a related post https://discussions.apple.com/thread/3274071?start=0&tstart=0. There is an issue with basic authentication and Http Redirect.

Portal with reverse proxy

I have been trying to implement my portal with a reverse proxy as described in the whitepaper Oracle9iASPortal Configuration Options dated Dec 2000. It hasn't gone well. I did get it to work on a plain portal with no users or customizations but now when I try to set it up with a portal with minor configuration changes, it no longer works thru the reverse proxy. Has anyone had success using Oracle9iASPortal v 1.0.2.1 with a reverse proxy?

The 9.0.4 Portal Configuration Guide has a section about setting this up:
5.6 Configuring Reverse Proxy Servers
The 9.0.4 documentation library can be found on OTN:
http://www.oracle.com/technology/documentation/appserver10g.html

Forms with reverse-proxy problem

Hi:
How can I use a reverse-proxy (apache) to correctly run Oracle Forms and Oracle Reports Standalone (JINIT or Sun JVM).
Do I need to configure formsweb.cfg? default.env? Can anyone help me ?
I've setup Apache reverse-proxy... and it runs... but i got frm-92101
Thanks
Joao

Hi:
I've set this on httpd.conf
ProxyPass /forms http://10.0.0.1:7778/forms
ProxyPassReverse /forms http://10.0.0.1:7778/forms
My Apache port number is the standard 80
Did you used these Apache directives to setup the reverse proxy? Are you using forms standalone or with sso ? This test case I've setup is used with Forms&Reports Standalone.
It always happens this problem.
EDITED:
I found the problem... the problem is the database... 11G!!! With 10G it works ok!
Thanks
Joao

Is this dynamic caching scenario possible with reverse proxy?

I'm considering using the Sun System Java Web Server as a reverse proxy in front of other SSJWS's running a java webapp. I'm creating a dynamic site where most of the pages change only occasionally. I'm wondering if the follow "dream compression/caching" scenario is possible:
- Origin web servers have a set of high traffic dynamic pages that change only occasionally. Other pages (could be partition in subdirs) should not be cached.
- These dynamic pages set cache and expires headers allowing browser and proxies to cache the content--say for hours or days. It's ok if users see a slightly stale page within this expiration period.
- Reverse proxy caches these pages as if they were static files. They also create gzipped versions on the fly and cache those. When requests comes in for these specific pages, they are served straight from proxy cache (either compressed or uncompressed depending on request header.)
- When the expiration date is reached, reverse proxy requests fresh pages from the origin server, creates a compressed version, and only servies these pages from cache.
- A certain set of pages shouldn't be cached and will have appropriate headers. They will probably also be in different subdirectories.
Is it possible to use the reverse proxy as a self-updating cache this way? (And it it possible to proactively invalidate the cache. Let's say I change a page on the origin and I want the proxy to refresh that cached page right away.)
Thank you,
Armando

I see. Thank you, this is very helpful.
I've take taken a look at Web Proxy 4. It seems it can do much of what I'd like. One downside I see is that it seems to be quite a big tool with all of the forward proxying features that I don't need. I just need a transparent reverse proxy/cache, so it would have been nice if the reverse proxy provided by Sun Web Server offered some of the caching features of Web Proxy 4.
Does Web Proxy 4 share code with Web Server? I haven't any seen any buzz, blogs, etc about it as I have with Sun Web Server. I see it now has a "modern HTTP core" and such but is performance on par with Web Server? (There are no trumpeted world records, and I don't see any architecture details, such as the ability to leverage event ports on Solaris...)
It looks like Web Proxy 4 can be configured as a reverse proxy to do sticky load balancing, caching with interval checks, and on the fly gzip compression. Can it: cache both a compressed and uncompressed version of the content? Run other filters on the content before caching, such as the sed content trip filter? I haven't really seen anything out there that can do all that. If this is possible, then Web Proxy 4 deserves more buzz!
If anyone has any good or bad experience using Web Proxy as a reverse proxy, I'd love to hear it!
Cheers!

Forms/Reports with Reverse Proxy and Load Balance

Hello Guys,
I want to setup an environment with apache as reverse proxy for uses with Forms and Reports.
Is there any special configuration? Or just config rewrite rules?
Something like this:
Users -----> NLB Device -----> Reverse Proxy (Apache - 2 machines) -----> Oracle Application Server (Forms/Reports - N machines)
Best Regards

I haven't made one, but I think it should work, just dont forget to use proxypass and prosypassreverse.

SSL tunneling with reverse proxy

Hi,
I have configured reverse proxy on Sun Web Proxy server. Now I am trying to configure SSL tunneling .
Steps followed :
1. Server Manager tab -> my server instance -> Routing tab.
2. Clicked the Enable/Disable Proxying link.
3. Created a new regular expression connect://.*.5000 (as my content server listens for SSL connections on port 5000.
4. Selected the connect://.*.5000 resource from the drop-down list.
5. Selected Enable Proxying Of This Resource and clicked OK.
But it doesn't seems to work, Is there a way to verify ? Does SSL tunneling applicable to reverse proxy ?
Thanks,
Nitin

SSL tunneling is a forward proxy operation.

Webdispatcher with reverse proxy

Hi Experts,
We need to deploy reverse proxy and web dispatcher. This is for a relatively budget savvy customer so cost is big issue. My question is :-
1) Can we deploy reverse proxy & webdispatcher on the same server ? (without using VMware). Probably we will use two Linux operating system.
2) Should we plan for failover on Webdispatcher ? Or running Webdispatcher without failover may not be that big issue.
Can you guys please share your thoughts on these two issues ? Urgently require your feedback on this.
Regards,
TB

Hi,
We need to deploy reverse proxy and web dispatcher.
The web dispatcher IS a reverse proxy. What do you mean ? I think you did not perfectly understand the need...
1) Can we deploy reverse proxy & webdispatcher on the same server ?
Yes, but it does not make sense to me until you have a very unusual requirement.
Should we plan for failover on Webdispatcher ?
If you need High availability, yes. You're the only one to know if you need it...

Olivier
