We have set up farm with 3 WFE's. Web apps are load balanced by hardware balancer with SSL. Assuming that our web site is https://www.foo.bar, we have our applications configured as follows:
- HTTP binding on port 80 with host header www.foo.bar
Alternative access mappings:
Load balancer is configured to communicate with WFE on port 80. Everything looks to work as it should - users can access site via https, and can log in with ADFS without issues. But they can't upload any document, because connection is reset by server. Same thing on pages where there is at least one postback. And this happens only on FireFox. On IE, users can do what they like.
There is also zone for internal access, with Domain-signed certificate running on port 443. This is also mapped to address https://www.foo.bar, but only in internal DNS. Accessing site internally doesnt show same sympotms - everuthing looks to be working fine.
There must be some kind of misconfiguration, but I can't work it out. This is our first deployment with hardware LB and SSL.
