In WAS, the default installation is an application server with an embbedded HTTP server to serves http requets. You can also install the IBM Http Server (IHS) as a standalone application, in front of WAS, on a different machine (or not), and configure the plugin to *link* IHS with WAS

What is the difference between Web server and App server in Websphere?
A few more related things -
A webserver can serve as a front-end gate keeper for a bunch of app servers behind. It can do load balancing. It can also do fail-over support, by routing the requests to a different server in the cluster (cloned server that has the same exact software running) and many other such things. This is typically what a stand-alone webserver(that is not integral part of Websphere) would be doing.
All that the app server knows is simply how to handle the http request it gets. [ February 11, 2005: Message edited by: Jayadev Pulaparty ]
