Support Multiple Web Roles with Host Header Redirection at the Load Balancer
Currently you can only have multiple web roles using different ports numbers. If host headers could be configured at the load balancer then different web roles in the same cloud service could be accessed over standard ports 80/443 using different DNS aliases. One reason for wanting this is multiple web roles that share dedicated cache roles.
Thanks for the suggestion.
Currently Azure’s Load balancer operates at Layer 4. it does not inspect the Http headers to make any decision. This will have to be done in the future through a Layer7 load balancer appliance.
