Hello,
If they are talking about a web server session, then that is entirely up to the web server unless you are using vCNS load balancing, then I do not think so. Session stickiness between protocols I do not think is supported but this is something you will have to test. The best thing to do in this case is attempt it, and see if things work as the developer expected. If in the webserver, that is a webserver issue, in the LB, then a vCNS issue.
Best regards,
