Load Balancing with ACE using HTTP Header information

Hello,
I am trying to setup a class-map using http loadbalance match-all.
What I want to do is check for the HTTP Host and if it doesnot match the http referer than go to server farm A. if it does match then go to server farm B.
My problem is the host can be serveral different values as well as the referer. Can you setup varibales in the ACE so I can store the value from http host and compare it against http referer?
Thanks
Mike C.

It should be like this (If you want to use separate class maps for referrer & Host).
class-map type http loadbalance match-any site1-HostHDR
2 match http header Host header-value ".*site1.com"
class-map type http loadbalance match-any site1-Referer
2 match http header Referer header-value "http://site1.*"
class-map type http loadbalance match-any site2-HostHDR
2 match http header Host header-value ".*site2.com"
class-map type http loadbalance match-any site2-Referer
2 match http header Referer header-value "http://site2.*"
class-map type http loadbalance match-all Site1-policy
2 match class-map site1-HostHDR
3 match class-map site1-Referer
class-map type http loadbalance match-all Site2-policy
2 match class-map site2-HostHDR
3 match class-map site2-Referer
policy-map type loadbalance http first-match Site1
class Site1-policy
serverfarm SFarm-A
class Site2-policy
serverfarm SFarm-A
class class-default
serverfarm SFARm-B

  • ACE load balancing and testing using soapUI

    Hey, I am trying to crowd source a solution for this problem.
    A client is testing using soapUI to an application that is being load balanced via ACE. There are two webservers behind the VIP servicing the client request. When client tests, requests are timing out per the soapUI log. A packet capture was taken and it clearly shows that ACE is not forwarding the HTTP data back to the client. When client tests by bypassing the ACE load balancer, it works fine. But, there are other clients from other applications that are making successful connection to the load balanced application via the VIP.
    Question, is there any thing unique with making HTTP/XML based requests using soapUI? LB configuration is shown below:
    class-map match-all EAI_PWS_9083

    Hi,
    Your configuration looks fine. I am not familiar with soapUI but if it is like a normal TCP connection followed by HTTP requests, i don't see why this shouldn't work.
    Do you know if there is a difference while using soapUI and normal request using browser?

  • ACE 4710 and load balancing with sticky cookie

    Configuring load balancing with SSL termination and stickiness for a couple of citrix xenapp servers.  I'm doing a source-NAT as the ACE resides in the DMZ and these particular servers reside on the inside arm of the firewall.  The ACE is in bridged mode to load balance web servers that reside in the DMZ.  Everything seems to work just fine, but the cookie stickiness does not seem to be working.

    Hi David,
    As you may know, using Wireshark to look at an HTTPS capture is only useful if you've installed the server SSL key.This is why I find it easier to use something like LiveHTTPHeaders or HTTPWatch.
    When using cookie-insert, the ACE will not create any dynamic cookie entries.  It will simply create one static entry for each rserver with a cookie value, such as R3911631338, and any client that gets load balanced to that rserver will receive a cookie with that value.  So what you see there is what is expected.
    You are correct in that when using location cookies that the server supplies, the ACE will create a dynamic entry when it sees the server response with the cookie.   The cookie is included in the server's response, and the ACE will look for the value as configured.  The cookie will also be sent to the client.  If the cookie is not in the server's first response, you will need enable persistence-rebalance so that it will look in subsequent server responses.  If the browser opens new connections with that cookie, then the ACE will stick to the same server.
    My suggestion would be to get sticky working with cookie-insert first.  Then if that meets your needs, go with that permanently.  If you need to use server cookies, then once cookie insert is working, migrate your sticky to cookie location.

  • Safari cannot load balance with https

    I am a developer for a web site which runs ASP.NET pages on Windows Server 2003, IIS 6.0. We use Basic Authentication and HTTPS.
    We are using a load balancing solution to distribute the load to 4 web servers.
    We have been using this setup for over 5 years with IE and Firefox/Mozilla/Netscape browsers.
    Recently I have been asked to make Safari browsers work with our site ... MAC, Windows and iPhone versions.
    On all 3 platforms I am seeing the same problem ...
    The load balancer uses the SSL 3.0 Session ID to determine if the requests to the site are coming from the same client (browser) and thus will ensure that all requests from that browser go to the same web server.
    This works fine with IE, Firefox ... it does not work with any version of Safari. When the load balancer gets a request from a single Safari browser session, it sends the requests to multiple servers, causing issues with the pages returned.
    If I run Safari with an HTTP debugger ... like Fiddler (where it uses a proxy server) ... Safari works fine.
    Some questions:
    1. Does Safari expose the SSL 3.0 session id in the same manner as the other browsers ... i.e. an un-encrypted version of the header.
    2. Does Safari send many concurrent requests? Firefox and IE limit concurrent requests to 2.
    3. Could Safari be timing out it's SSL 3.0 session id frequently or quickly?
    4. Is there a reason Safari does not send the http Basic Authentication header with every request once it authenticates with a particular realm?
    3. Are there any other possible causes of this problem?
    What do you think?

    Thank you for your reply.
    The session server id is being maintained by Safari and when the connections are kept on a single server (like when I use Fiddler's proxy to connect) it works fine.
    The SSL 3.0 Session ID is part of the SSL handshake which is used to establish an https connection. It is established between the browser and the web server as part of encypting the traffic.
    As I understand it ... part of the SSL 3.0 protocol is to include an un-ecrypted header along with the encrypted data.
    Our load balancing sofware is using a portion of this header (as it is un-encrypted and thus it can read it) to establish when requests are coming from the same web browser. This is the SSL Session ID.
    If the Session ID is the same, it will send all traffic to the same web server ... as it knows it is the same web browser.
    The problem arises in that the load balancer is not able to indentify requests from the same Safari browser as part of the same secure session.
    So I am trying to understand what Safari is doing within the SSL header ... as it is not normally visible to standard web debugging tools ... they only show the http headers.
    Unfortunately I cannot easily change out the load balancing software or change it to use session state ids. I am trying to understand how Safari handles this to determine strategies to resolve this issue ... and thus allow my client base to use their Safari browsers to access out service.
    What do you think?

    An 881 should be able to load share across multiple ports.  Many routing protocol support ECMP, including BGP, but you need "special" hidden/secret commands to enable.  EIGRP also supports unequal cost load sharing.
    If an 881 supports OER or PfR, those too will do unequal load sharing, dynamically.

  • 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.

  • CF 10 Load-Balancing with Remote Instances

    I was reading an article on Clustering/LB/HA using CF8, but have not found any updates for CF10.
    Using VM VirtualBox to setup a few virtual servers, I am looking to setup a load balancing of ColdFusion 10 on 2 remote instances. The goal would be have ColdFusion Cluster Manager be able to point http request to one of the two servers based on load/availability. Not really having a hardware cluster/failover setup, just managing resources on two CF instances instead of a standalone.
    The servers are Windows Server 2008 R2 with IIS7.5 and ColdFusion 10 Enterprise on installed on 3 of these machines. Let's call them CF-LBManager, CF-Web1, and CF-Web 2. In the CF Docs, they show the Cluster Manager adding the local CF instance and "if you want" a remote instance. However, this scenario would require the main instance to be running and not fail for it to direct to the other instance.
    I am trying to set this up now with CF-LBManager as just a manager of the requests coming in. In the Enterprise Manager >> Instance Manager, the local instance is shown and I add the two remote instances with the correct Remote Port, JVM Route, etc. I also made sure the <Cluster>...</Cluster> block was added to the two remote instances (CF-Web1 and CF-Web2) \runtime\conf\server.xml file too, Jetty Services also is running. Now under the Enterprise Manager >> Cluster Manager I add the two remote instances to the cluster, not the local instance on CF-LBManager with Multicast Port and Sticky Sessions enabled. On Submit, I get a green message "You must restart all the server instances and any configured webservers for these changes to take effect.". I go ahead and reboot the servers and come back.
    I now browse to the ColdFusion page as a test on CF-Web1 and CF-Web2 to make sure CF is running properly, they do. I then browse the IP of the CF-LBManager, however it only returns the local IIS web site and not redirect to one of the two cluster members. I am not seeing any message on the coldfusion-out.log on the remote instances. Am I not setting this up correctly or not enabling the Cluster Manager to take over and pass along the requests to those in the cluster?

    Unfortunatley I don't have a lot of experience with CF10 on Windows, but if you are running CF behind IIS I think  you will need to update the Tomcat connector configuraiton to do load balancing. I'm not sure if re-running the wsconfig tool on all of the servers will do this or not, but that is what I would suggest trying first. If that doesn't work you will need to update the Tomcat connector configuraiton manually. You can find more information on load balancing with the Tomcat connector here: http://tomcat.apache.org/connectors-doc/generic_howto/loadbalancers.html.

  • Load balancing with JSP

    Anyone and everyone,
    When configuring load balancing with Weblogic clusters, does load
    balancing take effect for all services or just EJB and RMI? Or another
    way of saying the same thing, can I setup weighted load balancing for
    the JSP engines across 2 weblogic servers.
    Thanks in advance,
    Mike

    The load-balancing documentation you read describing the different algorithms only applies to RMI stubs (e.g., EJB clients). Please see http://www.weblogic.com/docs51/cluster/concepts.html#1026091 for a description of how load-balancing/clustering works with servlets/JSPs.
    The short answer is that in using servlet clustering, most people want/need/use in-memory replication for HttpSession objects. In WLS 5.1 (and before), in-memory replication requires one or more proxy servers be set-up in front of the cluster. Typically, most people use something like BigIP to load-balance
    across the proxy servers and let the weblogic plug-in for the proxy server handle the routing to the cluster. The plug-in uses round-robin until an HttpSession is established for a user, then it always tries to route to the server where the user's session is located.
    Hope this helps,
    Robert

    All,

How about Weblogic handle weight based balancing after DNS round robin ip response? or just can choose one way instead of both?
    What's the big difference between choosing BigIP and software balancing (WL)?

    My 2 cents.

  • Load Balancing with BigIP / SSL question

    I have an oddball question. We're load balancing ColdFusion
    MX7 across 3 servers using a BigIP load balancing server. We
    decided to go the hardware approach and it has been great except
    for one small configuration issue.
    We use a mix of SSL and non SSL pages, prior to the switch
    from a single server to a load balanced setup I used to script that
    would determine if a page that was supposed to be SSL had the
    variable CGI.HTTPS turned on or off. If it was off, the page would
    redirect back to itself with the SSL turned on.
    The problem we have is that we followed BigIP's instruction
    to secure the load balancing hardware instead of the three servers
    running behind it. So what happens is that the traffic goes to the
    load balancer port 441, but then the calls from the load balancer
    to the individual servers is port 80. So even if a page is called
    as HTTPS://... the coldfusion server says that CGI.HTTPS is "off"
    since the traffic is port 80.
    This isn't much of a problem, our SSL pages are linked as
    HTTPS:// and the only problem would actually arise if someone was
    to type in the URL and call it as HTTP rather than HTTPS.
    My questions is this, does anyone know of a way that I can
    detect if the page should be HTTPS and is not without changing our
    configuration and putting SSL certificates on each individual
    server?

    Hey,
    Well the load balancing with the BigIP device is really very
    amazing. I think
    what i liked most was swapping out servers when their lease
    was up, through the
    BigIP manager I just stopped all traffic to a server, shut it
    down, plugged in
    the new one and turned traffic back on. It was really very
    easy.
    The SSL stuff still gives me a headache to think about. but
    I should mention I
    no longer work where I was, plus now I'm all .net C# but
    that's a different
    story.
    I think if I was going to do this all again I would not have
    secured the bigIP
    unit. It was nice to buy one SSL cert for all the servers I
    attached rather
    than one per server, but getting the SSL sites to work
    properly was a headache.
    We also use windows file replication where now I would go
    with like a pair of
    Dell MD1000's mirrored for storage and just have tons of ram
    and cpu on the
    front end units. Depends what you want to spend I guess. I
    think the bigIP unit
    we bought was like 20 grand, i think they are cheaper now
    though.
    Hope I helped.

  • How does load-balancing with WebCache work - is there still a bottleneck?

    Hello,
    We're migrating an old Forms 6i app to 10.1.2.0.2 (apps servers = Redhat Linux), and are starting to consider using WebCache to loadbalance between two application servers.
    My question is this - say we have apps servers A and B, both running Forms and Reports Services. We use Webcache on server A (don't have the luxury of a third apps server...) to load balance between A and B. So all initial requests come into A, which in some cases may then be diverted to start a new Forms session on B.
    For those users whose middle-tier sessions are now running on B - will all network traffic for their Forms session continue to be routed through Webcache on A, then to B, over the course of the session? Or does Webcache somehow shunt the whole connection to be straight between the client PC and server B, for the duration of that Forms session?
    If the former, does that mean that the server hosting Webcache can still be a significant bottleneck for network traffic? Have people found load-balancing with Webcache to be useful..?
    Thanks in advance,
    James

  • Load balancing effect on ssh/https connections

    We have a RV016 load balancing between two broadband WAN connections. On protocols that are sensitive to a change in IP address such as ssh and https, if the client connection goes inactive for a short time (sometimes as short as 10 seconds), the RV016 often changes WAN connection as part of its "load balancing" feature. Most protocols do not even notice, but the more sensitive protocols do and often lock a session or timeout the session which is not a good thing.
    We have been able to bind these sensitive protcolols to a particular WAN port but (in our minds) this is not an "ideal" situation. In fact I would consider this to be a broken "load balancing" solution and should be fixed.
    Does anyone have any "permanent fixes" or ideas on this?
    Thanks!

    Sorry Tom, but I wrote (edited for clarity): "What would happen [..] when the particular WAN chosen goes down? Does the system apply the same binding to ***another WAN*** until the original one comes back up, will it ignore the bining and so break any new sessions of the same protocol or will it simply fail (no connection)?"
    I did not write "the other WAN". That is, I am considering the case, quite common, of more than two WANs.
    Proper load balancing is described here:
    http://help.mysonicwall.com/sw/eng/305/ui2/23100/Network/WAN_Failover_Load_Balancing.htm
    "About Source and Destination IP Address Binding
    When you establish a connection with a WAN, you can create multiple interfaces, dividing up the task load over these interfaces. There are both Primary and Secondary WAN interfaces. This task distribution model maintains high performance, ensuring that one interface does not become an impasse to the point where it blocks traffic from passing. This process is WAN Load Balancing.
    While WAN Load Balancing addresses performance challenges, it can create other problems, including losing track of sessions. Session confusion can occur because some applications fail to adequately track multiple user sessions load-balanced on multiple interfaces. These applications treat incoming packets as originating from different users because they use IP addresses to differentiate user sessions instead of application-layer user identification tags.
    To ensure that you have proper connectivity in all applications, SonicWALL provides a feature called Source and Destination IP Addresses Binding, a solution that maintains a consistent mapping of traffic flows with a single outbound WAN interface."

  • T3 Load Balancing with Weblogic Server 6.1

    We are using rwo weblogic 6.1 servers A and B behind a load balancer with a DNS name (eg. www.loadbalancer.com). We are using T3 for Java client to application server communication. The client creates the Initial context with the load balancer url,creates remote objects using the context, closes the initial context and then tries to get a new initial Context. What we noticed is even though the client closes the first context and gets a new one, the client is always hooked on to only one server making load balancing ineffective. Is there a T3 configuration to release the connection when we close the context ? The documentation says only one T3 is established per client JVM.

  • Load Balancing with ASR9000 vN and multiple ISPs

    Hi,
    we will deploy a new DC as Active/Active.
    We will have ISPA and ISP B in each DC. Internet users are anybody in the internet coming to our e-commerce DC application.
    How could we do load balancing between ISPs using the ASR9001 and nV feature ?
    There is any IOS-XR feature that could help us about to do load balancing between ISPs?
    Thanks a lot.
    Regards,
    J

    You have 2 options here Jordi, either you can use BGP loadbalancing, this requires multipath as BGP by default would only install one route from the BGP table to the RIB hence FIB.
    But this may result in excessive IRL (inter rack link) usage in the cluster when traffic coming in on rack0 wants to take the bGP path out on rack1
    You could also use ABF (access-list based forwarding) to forcelly push traffic received on rack0 out on the link on rack0 and use an ipsla tracker to fallback to rack1 in case the uplink is gone.
    Alternatively to extend this by IGP signaling to redirect traffic preferably to rack1 to start with to minimize the IRL usage.
    And then you also have the ability to use RPL in the uplink path to make one link more preferred on teh internet then the other in case you want to control a bit which link is preferably used on rack0 or rack1

  • Multihomed eBGP load balancing with 3 ISP's

    We currently peer with 2 ISPs using BGP in an active/failover configuration.  My company wants to move to a 3 ISP model where Internet traffic is split across the 3 providers so that bandwidth is equally distributed on outgoing traffic across our 2 /22 ARIN IP ranges.  This is from our 2 edge switches that have VSS.  
    Within my limited knowledge of BGP, I have determined that we could do load sharing pretty easily by adding multiple default routes and breaking up our /22's into /24 and advertising them that way.  However, I don't think this satisfies the request that downtime must be seamless, should one link drop.  
    Currently, our ISP's advertise default routes.  From the research that I've done, we could get close to load balanced links if we receive full BGP routes and community settings and definitions.  I'm nervous about this because it looks really complicated, and I don't want our AS to turn into a transit AS.  I've been told the same can be accomplished with only partial BGP routes and community settings and definitions.  
    Personally, I think we just need a WAN load balancer.  However, given the request, is there a thread out there that can explain this, or can someone discuss this requested scenario a little bit?  
    Thanks!

    First question would be what is the required reconvergence time for the applications using the Internet? Should an outage occur, when do they lose their state? Once you know that, you then have a target to aim for in terms of recovery
    With regards load-balancing, with BGP we are always talking inbound and outbound.
    The outbound solution is relatively simple - each ISP advertises a default route to your Internet edge router(s). Create an eBGP session from each edge router to the core, advertise the default route and redistribute into the IGP. Ensure the IGP cost to each BGP next hop is equal and you have ECMP for outbound routing.
    Inbound influence is usually via MED (not likely in this case given 3 ISPs), adjusting local-pref in the ISP via BGP EXT communities configured your end, or via AS-PATH prepending for longer prefixes from your /22. Prepending would be simplest, but your unlikely to get an exact inbound traffic split, however a relatively even distribution should be sufficient.
