网站维护登陆页面

Question

This is a pretty lame question to begin with. We have a web application hosted with a cloud provider with the layers that the traffic needs to pass though.

A WAF ( Cloud hosted ) --> Load balancer ( Cloud provided ) --> Tomcat (instance )

We don't have a web server sitting in front of Tomcat. Wanted to know how others manage site outages, in terms on setting up a maintenance page and ideally where it should be sitting. When i mention site maintenance it's bringing Tomcat down. Apologies upfront on any ambiguities.

Answer 1

如果您使用的是Incapsula，则可以使用其“自定义错误”页面（仅适用于Ent客户端），一旦Tomcat关闭，用户将看到“ Incapsula错误”页面（由您自定义）。

Answer 2

使用Incapsula的自定义错误选项，或仅将DNS指向另一个静态来源（如Cloudfront或S3）
