Simple Two Server Reverse Proxy and Portal Config?

Hi, I would like to create a very simple two box configuration to access Oracle Portal from the internet.
Web Cache would run as a reverse proxy for login.mycompany.com and portal.mycompany.com with two IP addresses in the DMZ.
The second server would run the Portal Mid tier, the Infrastructure tier and the oracle database.
Is this configuration possible? The enterprise deployment guide uses 6 servers to do this. Can this be done with 2?

in the Enterprise Deployment Guide in section 9.2.3.4 Updating the httpd.conf file:
NameVirtualHost idmhost1.mycompany.com:7777
<VirtualHost idmhost1.mycompany.com:7777>
ServerName login.mycompany.com
Port 443
RewriteEngine On
RewriteOptions inherit
SimulateHttps On
</VirtualHost>
In Section 9.2.6.1 ensuring Validity of Self-Referential URLs Rendered on OracleAS Portal Pages is updates the portal's http fil
<VirtualHost apphost1.mycompany.com:7778>
ServerName apphost1.mycompany.com
Port 7777
RewriteEngine On
RewriteOptions inherit
</VirtualHost>
I don't understand how all the ports map to different services when the infrastructure and portal tier are installed on the same server. But is the port 7777 in confllict? Is the Guide in section 9.2.6.1 using Port 7777 to connect to the web cache listening port?

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...

ISA Server Reverse Proxy and SSL

We are running ISA 2000 and EP6SP2 and have successfully configured SSL between the internet and our ISA server which is located it our DMZ. Result when you access the portal URL you have the padlock in the browser, when you have logged onto the portal the padlock disappears. Does anyone have any advice / documents on how to configure the next step which I believe is SSL between ISA server and EP6SP2 ?
Any advice would be apreciated.
Thanks

Hello Alex,

Reverse Proxy and Load Balancer for SMP 2.3 and Agentry Application

Hi Expert,
I'm putting in place a mobile solution composed by SMP 2.3 SPS 4 and SAP ECC 6.0. In the SMP 2.3 I created the agentry server and I have deployed my agentry application.
My SMP/Agentry infrastructure is composed by two servers therefore I need a load balancer for balance the load into the several servers. Furthermore I need to use a reverse proxy in my DMZ zone.
Based on what indicated in the SAP note "1904213 - SAP Mobile Platform Server Release Information" the Apache Reverse Proxy is not supported for Agentry clients. Agentry uses nginx for Reverse Proxy.
I also found the following document How-to-Guide for Reverse Proxy and Load Balancing in SAP Mobile Platform 3.x that explain how to set-up a reverse proxy and load balancer with nginx and apache.
Both the SAP note and the HOW to document are refereed to SMP 3.0 and not to SMP 2.3.
I would know if the NGINX must be used also for SMP 2.3.
Any suggestion/information is appreciated.
Thanks in advance
g.

Apache reverse proxy and SSL termination

Hi Guru's
Can anyone tell me, how to do SSL termination at apache reverse proxy. I am using apache reverse proxy for accesing portal from internet. Apache is configured for SSL and portal is NON SSL.
I am using header variable login module in portal. i wanted to terminate SSL at apache reverse proxy and then all traffic after that should be clear text.
should i maitain any property. is there any documentation for it.
Please help me
Tom

The majority of the work here is around configuring your Web Dispatcher and Apache Reverse proxy. The work on the portal is straight forward enabling of SSL.
You can follow http://help.sap.com/saphelp_nw2004s/helpdata/en/f1/2de3be0382df45a398d3f9fb86a36a/frameset.htm for setting this up.
what level I need to configure SSL and how do I proceed in both scenarios?
Your question itself says where you need SSL. SSL is required where ever you need HTTPS communication.
how do I proceed in both scenarios?
From a portal perspective, the configuration should remain the same.
Do I have to install SSL at portal, web dispatcher or at Apache level?
SSL needs to be configured at all the 3 levels if you are looking at end to end SSL implementation.
See the following for possible SSL implementation options:
http://help.sap.com/saphelp_nw04/helpdata/en/d8/a922d7f45f11d5996e00508b5d5211/frameset.htm
https://cw.sdn.sap.com/cw/docs/DOC-115509
Will SSL termination work for scenario 2?
Yes this should work - see http://help.sap.com/saphelp_nw2004s/helpdata/en/36/fd39eacf4cde4a8fe32d7f29b3db16/frameset.htm
However in case of SSL Termination, the request to your portal from the web dispatcher will be sent as HTTP.
I would recommend you to take a step by step (backward approach).
First, enable SSL on your portal and make sure it works - going directly to the server.
Then, you can introduce the Web Dispatcher - and test if every thing works going through the web dispatcher.
Finally - you can test the end to end flow - with your Reverse proxy involved.

Arrowpoint Cookies, Reverse Proxy and Multiplexed Client Requests

Hi,
I have a reverse proxy which is performing SSL offload and making backend connections to two web servers. Between the reverse proxy and the two webservers, a CSS is in place to load balance between the web servers. There is a requirement for session stickiness on the web servers and since client IP details are lost through the reverse proxy I have used the arrowpoint-cookie method to load balance connections.
However, the reverse proxy seems to make only a handful of connections to the servers compared to the number incoming client connections and we have noticed that stickiness is broken. Now, I would assume this is correct if arrowpoint-cookie makes a load balancing based on the first HTTP get in a tcp stream and not on a per transaction basis AND our reverse proxy is multiplexing client requests. However, I can not convince myself of how the arrowpoint-cookie method actually works.
I wondered if anyone had any insight on this or had experienced similar issues with arrowpoint cookies?

Hi Gilles,
I have implemented this today, and we are still seeing issues with requests hitting the wrong server.
A bit more info, the reverse proxy is an AXG Web Aopplication Firewall. I have been looking at this and am considering disabling connection re-use on here.
However I am also wondering if this might be to do with the flow timeout multiplier I am using which is 5 (80 seconds). Perhaps this is too low?
Thanks, David.

Need in depth knowledge about Certficate request and install for Reverse proxy and CAS role

Hi,
I have few confusions about Exchange 2010/13 certificate request and install. As per my understanding best practise is to assign public CA certificate to Reverse proxy and Local CA certificate to CAS servers but need to know that what should be the format
of certificate request? Do we need to order public certificate just for mail.domain.com and add SAN for other web services URLs and is it required to add CAS array and server names to this certificate ? In what case we will add server names and what will happen
if we don't add in it ? How the outlook clients connecting from internet will be using this certificate? I have very limited knowledge in certificates and it always pisses me off. Please help me with explanations and articles. I tried to google and gone through
many articles but didn't get a fair idea. Thanks in advacnce. :)

Hi,
Here are my answers you can refer to:
1. Use the New-ExchangeCertificate cmdlet to generate a new certificate request:
New-Exchangecertificate -domainname mail.domain.com, autodiscover.domain.com -generaterequest:$true -keysize 1024 -path "c:\Certificates\xxxx.req” -privatekeyexportable:$true –subjectname "c=US o=domain.com, CN=server.domain.com"
2. CAS array name doesn’t need to be added in the certificate:
http://blogs.technet.com/b/exchange/archive/2012/03/23/demystifying-the-cas-array-object-part-1.aspx
3. It depends on the situation that you configured to add the server name.
4. Outlook clients use certificate for authentication.
If you have any question, please feel free to let me know.

Web Dispatcher - Reverse Proxy and Load Balancing

I'm finding limited docs on Web Dispatcher with regard to reverse proxy and load balancing. Are you aware of some recent presentations or docs in this area? The info on help.sap.com is not what I'm looking for.
Thanks.

Hi,
best thing is that you look at your scenarios and test the web dispatcher against each of it, like:
- SSL
- Portal only
- Web Dynpro ABAP / Java
- BSP
- Different backend systems like SRM, MDM
- Several backends with 1 Web Dispatcher
After getting a list of use cases that you can test quite easily (installation of Web Dispatcher is done fast and can be done on a local PC), you can contact SAP Support and ask them about the specific problems and questions you encountered. This way, you'll get the official answer, sometimes they will even inform you about "secret" parameters and options.
As of the reverse proxy functionality: there are several version of Web Dispatcher available that differ from the functionality offered. The latest version - 7.2 - is the one that offers the most, i.e. allows you to create rewrite rules like Apache.

Reverse proxy and iWS 6.1 SP2?

Hey all,
i have 2 questions.
Can i use reverse proxy (and pass proxy) with iWS 6.1 SP2?
How must i configure the webserver to use this?
I need the following thing:
Client called https://server111.de/XXXXTruePassApp/ ---> Proxy get Data from https://server222.de/XXXXTruePassAppProxy/
Under Apache looks like that with mod_proxy:
ProxyPass /eCaSSTruePassApp/ https://server222.de/XXXXTruePassAppProxy/
ProxyPassReverse /eCaSSTruePassApp/ https://server222.de/XXXXTruePassAppProxy/
Thanks for help.
Greets Chmeee-de

Chmeee-de, I really don't think you should be using Sun ONE Web Server 6.1SP2. That version has known security vulnerabilities. Please consider applying the latest service pack, 6.1SP7.
Have you downloaded the Reverse Proxy Plugin? Have you tried reading the Reverse Proxy Plugin release notes? The release notes for Reverse Proxy Plugin 6.1SP7 are at http://docs.sun.com/app/docs/doc/820-0262/6nc0vpnc2?a=view.
Once you have the plugin installed and have edited the magnus.conf configuration file according to the release notes, you can add the following line immediately below the <Object name="default"> line in the obj.conf configuration file:NameTrans fn="assign-name" from="/XXXXTruePassApp/*" name="XXXXTruePassApp"This line indicates that requests for /XXXXTruePassApp/* should be serviced by an object named XXXXTruePassApp.
You can then create an object named XXXXTruePassApp by adding the following to the bottom of the obj.conf configuration file:<Object name="XXXXTruePassApp">
Service fn="service-passthrough" servers="https://server222.de"
</Object>

Reverse proxy and logs in Proxy Server 3.6SP2

Hello ALL!
I am using Cache server as a reverse proxy. I setup it for one internal server. It works great.
Now I am trying to use Virtual Multihosting. So I made mappings as required:
host1.domain.com -> int1.domain.com
host2.domain.com -> int2.domain.com
It works.
But server logs requests for all servers into one file. I need to have separate log for each virtual host.
I've made templates like
http://host1.domain.com.*
http://int1.domain.com.*
http://host2.domain.com.*
http://int2.domain.com.*
and setup log for each.
None is working. Only "entire server" logs.
Please help me separate logs.

Yes, it is possible. You have two options:
1. Use the same virtual server class for both virtual servers and use the <Client> tag to specify urlhost-specific configuration.
2. Use a separate virtual server class (with a separate obj.conf file) for each virtual server.
With option 1, part of your obj.conf file might look like the following:<Client urlhost="www.server1.com">
NameTrans fn="assign-name" from="/app1(|*)" name="passthrough"
</Client>With option 2, you would configure the Reverse Proxy Plugin in only one of the two obj.conf files.

Hello,
Thank you to interest to my problem.
Browser -
SSL----
> Firewall/DMZ (No SSL termination, all traffic forwarded to ISA Server). Yes but there is a port translation port 443 to 50201
Firewall/DMZ -
SSL----
> ISA Servrer -- (SSL Termination)--. IN fact it is noit the ssl terminaison. But from this point the url is modify to reach the host with EP7.0
ISA Server--SSL--
> EP7.0 (port 502010) When I test my configuration I have the Message web page not found. With a capture software i have verified that the request is sent to my EP 7.0( url2). But no logon page appeares. With the modification on line of the HTTP provider in the dispatcher, i have checked that the response contains the URL1 and the standard port. But none web page is displayed.
Thank you for your help.

Reverse proxy and monitoring

Hi
I'm using ep6 sp2 and it's working very well.
In front of was i have and IIS that it's acting as reverse proxy.
Now i want to make in portal an application for monitoring users, pages or ip-s.
The problem is that when i make in my iview request.getRemoteAddresse i get 127.0.0.1 (ip of my machine that make reverse proxy).
It's there a way how to get in my iview the original ip of the request?
Thank you.
Florin

Hi,
Yes , you can associate multiple FE pools with one edge pool/server for external access.
No , director server is optional. You can continue without director server role.
Yes , same monitoring server can be associated with multiple pools.
http://technet.microsoft.com/en-us/library/gg398199.aspx
You need to publish external web services separately for each pool , but simple URL can be the same.

Reverse Proxy and OWA

Hi,
Setup:
3 CAS servers - Exchange 2010
1 IIS ARR reverse proxy
I followed these two
1 2 write-ups on how to setup Exchange 2010 OWA to use IIS ARR as a reverse proxy. The problem I'm having is
when all three servers are online in the server farm OWA doesn't work properly. You can log in fine, but it appears to not load fully and you can't click on anything (eg Calendar, emails, forward, reply, etc). If I were to take all the servers offline except
for one (doesn't matter which one), OWA functions normally.
Since some users also access OWA internally I have configured IIS on each CAS server to redirect to HTTPS and the OWA virtual directoy. I don't think this is causing the problem, but I thought I should mention it.
I followed the articles exactly. I'm not sure what could be causing the problem.
Thanks

Hi,
According to your description, there may be some problem on the configuration of your IIS ARR.
Thus, let’s troubleshoot ARR using Failed Request Tracing Rules to find the root cause.
For the detail steps, please refer to the following article:
http://www.iis.net/learn/troubleshoot/using-failed-request-tracing/using-failed-request-tracing-rules-to-troubleshoot-application-request-routing-arr
And we can also check if the URL rewrite rules are working as expected:
For more steps, please refer to the partition named Verifying if the above rules are working as expected in the reference below:

IIS Reverse Proxy and Basic Authentication

Hi,
we've currently put a WebAS 6.40 serving a BSP Application in our Appl-DMZ. For the access via Web the IIS Reverse Proxy is used, which works fine as long as you use a service for which a user is provided (in SICF). But if you don't provide a user in the service (in order to debug the BSP Application) you have to authenticate yourself using Basic Authentication (Browser Popup) which does not work (the popup returns and returns ...)
I' ve browsed the forums and it seems that the IIS Reverse Proxy does not support (the forwarding) of Basic Authentication "requests".
So my question, does someone exactly know if the IIS Reverse proxy supports Basic Authentication or not ?
Thanks,
Markus

Hello Markus,
1. have you checked out Alon Weinstein's Weblog <a href="/people/sap.user72/blog/2005/02/23/the-reverse-proxy-series--part-2-iis-as-a-reverse-proxy">The Reverse Proxy Series -- Part 2: IIS as a reverse-proxy</a>?
2. Is the IIS a must? Can you give Apache or SAP Web Dispatcher a try. Prakash Singh wrote a Weblog <a href="/people/prakash.singh4/blog/2005/08/16/how-to-setup-webdispatcher-to-load-balance-portal-in-a-clustered-environment">How to setup webdispatcher to load balance portal in a clustered environment</a>.
