Hello,
Does Azure Application Gateway support sticky sessions (much like how azure load balancer offers)?
We have a hosted application (IaaS application) to which clients do an always connected secure web socket (wss) connection. Today our hosted application is behind an F5 loadbalancer which supports sticky sessions. We are moving our stack to azure iaas and hence the question.
Hi,
Yes, it supports cookie-based affinity. Please see article below:
Application Gateway HTTP settings configuration - Cookie-based affinity

Thanks.

I saw that but the layer 4 load balancers we use today do sticky session based on client IP (I don't think that is same as cookie based affinity as far as we know). So, can app gateway do sticky session based on the client IP much like azure load balancer does? (i.e. this: https://social.technet.microsoft.com/wiki/contents/articles/51997.azure-configure-load-balancer-for-sticky-sessions.aspx)
Application Gateway is a layer 7 balancer. So it allows you to do things like route based on URL for example. From your description, it sounds like you may be wanting a layer 4 balancer, which in that case you would use Azure Load Balancer.
It doesn't do layer 4 session affinity (e.g., by client IP). Do you have use case where you are wanting to have some of the layer 7 features but with session affinity decisions made at layer 4?
