MVC HTTPS redirection when behind a load balancer

由 我与影子孤独终老i 提交于 2019-12-12 03:35:15
问题 I'm using MVC5 in some IIS servers on Amazon EC2, behind a Amazon Elastic Load Balancer. IIS servers runs only HTTP protocol, and ELB converts to HTTPS. IIS server doesn't know if user is accessing thru HTTPS, so I have a rewrite rule checking "X-Forwarded-Proto" header to redirect user to HTTPS. Unfortunately, when a login is required, MVC/IIS redirects user to a logon page in HTTP . If I check my website in a tool like http://www.redirect-checker.org/ I get these type of results: http:/

问题 Our .net core web app currently accepts websocket connections and pushes out data to clients on certain events (edit, delete, create of some of our entities). We would like to load balance this application now but foresee a problem in how we handle the socket connections. Basically, if I understand correctly, only the node that handles a specific event will push data out to its clients and none of the clients connected to the other nodes will get the update. What is a generally accepted way

AWS Network Load balancing - session stickiness not consistent

由 落花浮王杯 提交于 2019-12-08 09:12:04
问题 We were using Application Load balancers earlier and session stickiness worked like a charm. Recently, we switched to the network load balancing and it's not working consistently, to make it worse we don't find any mention of session stickiness around network load balancers. We have the target groups as the backend application servers. Is network load balancer even an option for our use case? 回答1: I think, session stickiness won't be possible on a TCP level load balancer. The ELB use cookies
