It depends.

Modern web services are split into at least static content and dynamic 
content.  This divides up work, keeps cookies separate, and makes it 
easy to later push the static content to edge caches.

In the early 2000s it was common to put Apache in front of Tomcat via 
specialized software endpoints.  Sometimes it was to use Apache as a 
cheap load balancer and SSL endpoint.  Most of the time it was for 
entirely superstitious reasons.  The combination has poor performance 
and it's combining the bugs of two applications that struggle to support 
advancing technologies.

Jetty + Nginx is a more modern configuration of the two layer design 
that's popular with startups.  It's not optimal but it can be deployed 
on cloud services to avoid big up-front hardware costs.
