Hi,
We are running DNN4.9.5, and we have run into an issue. We have 2 webservers, and a pass-through load-balancer in front of them. We've been told by our infrastructure guys that the load-balancer will maintain server affinity only per protocol (so as long as you stay on http, you always go to the same server, but if you go to an https page, you might get redirected back to the other server). We've already seen this wreak havoc with our OWS custom modules, as if the page is flagged as https, it looks like the ows ajax calls are being handled in http.
We can work with R2I if this turns out to only be an issue with ows, but my bigger concern is if the DNN core or other 3rd party modules will have problems with this lack of affinity. I've looked into using sql server as the session state server, but there were a few posts here that said certain versions of DNN don't seem to like this solution.
Anyone have any experience with this? I can see dotnetnuke.com is using both http and https, and I believe they said a while back they were back on a webfarm environment, so it must be possible.
Anyone have a recommended solution to this? So far, we've been told the load balancer has no way to keep affinity across protocols, as that would seem to be the best solution if possible.
thks,
Phil
