Using WL8.1 to redirect traffic without caching

Hello All,
First off, I'm no web developer or Weblogic Guru, but was hoping someone might have some insight.
I have a https load balanced application (PeopleSoft) in which I'm going to put a maintenance page before the application. If the load balancer sees the http maintenance page up (health checks), it will direct traffic to the maintenance page web server IP, instead. I will also have an emergency page that if both the maintenance page and application webservers are down, traffic will be redirected there.
As the application stands today, the user hits the load balancer which redirects to the welcome page (currently index.html), which in turn redirects to the http<b>s</b> application URL on the same server (probably not the cleanest way to do this) via a HTTP refresh.
The load balancer and only redirect to a port and IP, not a URL. The maintenance page, application, and emergency page will all sit on separate WL 8.1 webservers.
Here is the issue: when the maintenance page is brought up and traffic is directed by the load balancer to that web server, if the Internet Explorer temporary Internet files are not purged, the default page (a web page with some system down info) is not displayed to the user. Instead, the browser attempts to use the cached refresh to the application's login page, which of course doesn't exist on the maintenance page's webserver.
I have tried to use variations on the following HTTP, but it doesn't appear to prevent caching of the refresh.
<HTML>
<HEAD>
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">
<TITLE>EMDMO Redirect Page</TITLE>
</HEAD>
<BODY>
<META HTTP-EQUIV="Refresh" CONTENT="0;URL=http://63.240.173.221/emdmo/signon.html">
</BODY>
</HTML>
I have also tried to set the welcome page in web.xml to the respective pages on each server, but apparently there's some caching involved there as well.
Does anyone have any recommendations as to how to handle this? I assume that Weblogic can be used to handle a redirect to a specific application or other page.
Any input is appreciated!
Avery

If your route point is a router or L3 switch then you could configure a route-map with an ACL that is used to change the next hop ip for the servers in the DC to the DRC. This will be a lot of manual configuration and testing but it maybe a viable solution.

Using APEX as SSO redirect for existing web application

Hi,
I have an existing PHP based Web Application hosted on an Apache server. I want to protect these web pages by authenticating users via Oracle SSO.
I tested this by creating a simple APEX web page with redirect <Meta> tag to route traffic to my application upon successful SSO login. This works fine if request comes directly to APEX page....
So my question is how do I protect php pages from being directly accessed and still be able to get sso user login information (like username) coming from APEX page?
Do I still need to set up mod_sso.so in osso.conf for my Apache Server or should I just register my php web application as partner application with SSO server without going through APEX?
Any advice on this is greatly appreciate.
Thanks,
james

Tony,
Sorry for taking so long to respond as I got side tracked with other tasks.
Thank you so much for the link. The provided link is very helpful.
One difference in my situation is that I am using a generic Apache installation (version 2.2.11) and not Oracle Apache Server from OAS.
So I copied mod_osso.so from OAS 10.1.3.1.0 installation to my generic Apache location. As I tried to startup Apache instance I got following error while loading mod_osso.so.
... Cannot load /apache-2.2.11/modules/mod_osso.so into server: /apache-2.2.11/modules/mod_osso.so: undefined symbol: ap_configtestonly
I did some search and found that other folks are reporting success of using mod_osso.so on generic Apache (without saying which version of Apache). I wonder if mod_osso.so can only work with older version of Apache?
Do you have insights on this by any chance?
Thanks again,
James

Cisco WSA : Is it possible to use web proxy in transparent mode without WCCP router ?

Hello !
I would like to use Cisco WSA as a web proxy in a transparent way (without any configuration in client's web browsers) but i don't have a WCCP router. So, is it possible ?
If yes, how to do this ?
Thank you,
Stephane Walker

Hi Stephane
The only alternative to WCCP is PBR (Policy Based Routing). With a simple configuration on the router you can redirect traffic defined as interesting by access list to WSA. On the WSA you need to configure transparent mode (Security Services -> Web Proxy -> Edit Settings -> Proxy Mode: Transparent). You also need to assure that proxy is listening on the port 80 and that HTTPS proxy is enabled (on port 443) if you want to redirect the HTTPS traffic as well.
Sample configuration for Cisco router
access-list 110 permit tcp any any eq www
route-map proxy-redirect permit 10
match ip address 110
set ip next-hop xxx.xxx.xxx.xxx
interface ethernet0/1
ip policy route-map proxy-redirect
xxx.xxx.xxx.xxx is the proxy IP in such case and access-list 110 defines web traffic (HTTP TCP/80) as interesting.
The biggest disadvantage of such solution is lack of failure detection. If the proxy will go down for some reason router will keep redirecting the traffic causing internet access outage.
Routers other than Cisco equipment should also have an option to configure policy based routing.

Ps. It's not possible to place the WSA in-line between clients and the internet.

Redirect traffic destined for an IP on Server 1 to go to Server 2 at DR Site?

DNS is what I'm using for most of my subnets. The problem is that I have a handful of subnets that have devices that are under the control of an outside agency. Those devices access a server in my DC by pointing to the IP Address.
If I performed a failover test to Server 2 at a DR Site, how can I redirect traffic from those subnets to Server 2 if they are still pointing at the IP on Server 1? In the DC, a 6509 sits between Server 1 and the subnets in question. To get to Server 2 at the DR site, I have an FWSM in the DC and an ASA5585 at the DR site.

If your route point is a router or L3 switch then you could configure a route-map with an ACL that is used to change the next hop ip for the servers in the DC to the DRC. This will be a lot of manual configuration and testing but it maybe a viable solution.

Redirecting traffic on SunOne 6.1 SP4

hi all,
i've got a web server running SunOne 6.1 SP4, and im trying to figure how to redirect traffic from 2 different locations.
the web server is accessed both thru the LAN and the Internet. how is it possible to re-direct traffic coming from an internal UP to another interanl IP and traffic from an external IP to an external IP.....?
currently im using the following in my obj.conf file. but this is re-directing all traffic to one location.
<Client security="false">
NameTrans fn="redirect" from="/" url-prefix="http://x.x.x.x/"
</Client>
how can i configure this to re-direct traffic coming from the LAN (these come from a 10.1.x.x segment) to another internal IP and traffic coming from the web to another external IP...?
any help on the matter would be highly appreciated.
thanks and regards,

To Documentation team,
Here is what to do :
update in http://docs.sun.com/app/docs/doc/820-1643/6nda4qg75?l=en&a=view#abvau
Old Text :
<Client ip="~192.85.250.*">AddLog fn="flex-log" name="access"</Client>
New Text :
<Client ip="\*~192.85.250.\*">
AddLog fn="flex-log" name="access"
</Client>
Note that a * (asterisk) is required before ~ (tilda) and make these 3 separate lines.

How to do a PortForward/Port Proxy? Redirecting traffic from port 8080 to 80 on the SAME machine

We have a CFTV system running on Win2008R2 that listens on 4 sequential port numbers and the last port is the Web Browser Port number for management and viwing cameras
When we configure the port 8077 on the software, it opens 8077, 8078, 8079 and 8080 and works with no problem
But...
When we try to configure ports 77 (and therefore 77, 78, 79 and 80) thw applications hangs and seems like not be possible to configure to use port 80
I could confirm that, using NETSTAT and the main CFTV application open all required ports with no problem, but only works on ports with a different number from "80", wich is what i want, to make users more confortable, avoiding to type ":PORT_NUMBER"
after the URL, it will be more "ellegant" solution to use default port 80 for user´s connections
The question is: How to do a PortForward/Port Proxy? Redirecting traffic from port 8080 to 80 on the SAME machine?
May i Use NETSH? (based on Help, it can be used to do this, but on different machines, not the same one)
There is a RELIABLE application, running as a service, that can do the port forward/redirect?

Hi,
I’m sorry to tell you that we can’t redirect traffic from a port to another port on the same server itself. But we can do it with a router which is configured to portfoward.
By the way, according to your description, another program may use the port 80. Is there an IIS installed on the server? If it is necessary, you can consult your CFTV system vendor.
Hope this helps.

How to setup CSS as reverse proxy server without cache server

Hi, question regarding CSS capabilities.
Is there a way to setup CSS (11000 series or 11500) to act as a reverse proxy server without caching server in place? Or is it possible for CSS to cache contents on its own?
And what is disk space on CSS used for?
Thank you.

Thank you for clarification on disk usage on CSS. I have gone through sample config for reverse proxy caching
http://www.cisco.com/warp/customer/117/CSS_CEreverseproxy.html
Does this mean only way to have CSS to do reverse proxying is to have cache engine in conjunction with CSS?
Thank you again in advance.

I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV?

I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV? I have a MiniDisplay Port to VGA adapter, but there are two issues with it: The new display doesn't have a VGA port, and even if it did, I wouldn't want to have my mac constantly attached to the display by a cable. I was looking for a way to use the TV as a display without any wires. Is there some type of bluetooth setup I could use? Please let me know if you have any suggestions.

As I wrote above, I think you should look into the Apple TV yourself. The best place to find information about what it can and can't do and to ask your own specific questions is probably in the Apple TV forum, here:

How do I use my ipod in the car without it constantly charging? I have to use a docking cable into the USB port because the 3.5 mm to 3.5mm jack I bought doesn't work on the ipod.

How do I use my ipod in the car without it constantly charging? I have to use a docking cable into the USB port because the 3.5mm to 3.5mm jack I bought doesn't work with the ipod (although it does work with an MP3 player). My ipod is a 5th generation 80GB classic.

I know this is old - but did you ever get this working. Thinking of getting a 780 ti card and I have an older mac with the mini-displayport too.

Can I use my G5 on the web without antiviruses ?

Hi guys and girls,
Could you tell me if I can use my G5 on the web without antiviruses ?
If you are disagree, please tell me which antiviruses is the best for you ?
Thanks.
Philippe

Welcome to the Apple Discussion Forum!
Currently no internet virus protection is needed for Apple OSX. Using Safari or Firefox is the best way to access the internet.
In addition, make sure you download and install all Apple Security updates (from the Software updates tab). This will keep your MacOSX protection up to date. In addition, there are only three Anti-Virus software programs available from the Apple store, that alone will give you a clue to the need for them.

Dave

How can I use iTunes on my new computer, without lossing all my music?

How can I use iTunes on my new computer, without losing all my music?
I don't want to rebuy everything I have purchased over the years.
Your help would be greatly appreciated.

They should be in your itunes media folder. Use an external hard drive and just copy that to your new computer. I'm sure there's an easier way like this one (iTunes>File>Library>Export Library>External Hard Drive) but I never tried it before. Anyways, once that's done, just simply authorize your itunes account to play music you bought on to the new computer.

My wife and I have separate have separate user accounts on our IMac. We have separate Apple IDs for iTunes. How can we use iCloud on our separate iPhones without sharing contacts, calendars, etc.

If have separate iCloud accounts and want to keep your all your iCloud data separate, you can create separate user accounts for each of you, then sign into your individual iCloud account within your user account.
If you want to just add both iCloud calendars on your Mac, you can sign into one iCloud account in System Preferences>iCloud, then add the second account in System Preferences>Internet Accounts>iCloud and only check Calendars with this second account.

Can i just partition my HD by using boot camp 4.0.1 without install window?

Can i just partition my HD by using boot camp 4.0.1 without install windows?
cox i want to use rEFIt to boot up my pendrive to install windows.
Due to some reason the boot camp 4.0.1 cannnot detect my usb drive (that contained windows 7), so thats why i use the rEFIt to boot from my usb drive

Yes, you can.
Let the BootCamp Assistant just make the partition and do not click on "Install Windows"-button.
The result is a preformatted FAT32-partition on your Mac.
