We have an F5 load balancing a pool of 2 Orion additional websites which both connect to one central NPM poller. The Orion database is on a separate server. The F5 hosts a certificate and we use https to connect to the website from the Internet. Everything works fine until you try to edit a node. For example if I'm at https://OrionWebServerPoolFQDN/Orion/Nodes/NodeProperties.aspx?Nodes=... and if I make a change then hit either the SUBMIT or CANCEL button I get an instruction to pull an http page which tries to open a new session. Since I was already in an https session before I hit submit or cancel, I cannot open the new http connection. The end result is I have hit the back button on the browser several times to reconnect with my https session. Usually the change I tried to make does take effect however this is a big nuisance problem since I can’t return to the node details page where I started. This issue even occurs with only one server in the pool and it to be bad a http-redirect programming in the Orion web application. You can clearly see the issue in a packet capture.
I had opened Case # 642678 but my ticket was closed with this response: "As confirmed by our dev team Orion NPM may have issues on a load balancer. From my investigation, the issue appears to be present on other web applications as well. I have to close out this case but I can place a feature request for you to add support for load balancers in Orion."
I don’t know if a feature request was ever opened by the tech support staff so I’ve opened one here.
