Appreciate all the input! Those things were already part of my list that are mentioned in this email. What I was trying to point was that we are really in restrictive env where server A can't be changed and 3rd party may not agree to change. So I was wondering if there is something like caching

Currently, the load balancer don't provide the user stickyness/persistence for 'x' amount of time. At this point only option I see is that of creating a custom solution. It looks like there is no good solution. Problem here is User can be directed to any site by load balancer in active active

Also the difference between GTM and LTM is that GTM enables fail-over between geographically different sites and for LTM that is possible only for local sites. Nothing to do with the persistence feature. On Wed, Mar 30, 2011 at 10:59 AM, Igor Cicimov icici...@gmail.com wrote: Strange because a

But this doesn't work for scenario that I described where user connects to server and then server sends the requests to us. We really want to load balance users not the servers. On Tue, Mar 29, 2011 at 5:07 PM, Igor Cicimov icici...@gmail.com wrote: Also the difference between GTM and LTM is

Aren't the requests from one user coming from the same ip? This method will cause the requests coming from one source ip address always go to the same server ip address ... but as I said maybe I'm missing something :) On Wed, Mar 30, 2011 at 12:18 PM, Mohit Anchlia mohitanch...@gmail.comwrote:

Apache 2: We use apache 2 and we have 2 data centers. Problem is that both data centers are active. So if User uploads a file for eg: in site A that User can be directed to site B. Files are kept in sync asynchronously. And it could take as long as 1 hr to bring them in sync on the other data

Thanks! We are using F5 GTM as global load balancer with LTM. So global load balancing is not a problem. Problem is user stickyness that need to persist beyond individual session. I forgot to mention that the problem is that these connections come from the servers using http rather than browser
