I have a webapp that I would like to behave in a context (actually host)-specific manner. Where is the best place to initialize the context/host specific functionality?
Let me demonstrate what I'm talking about. Lets say I have a webapp Fruit located in folder webapps/fruit. I want to define: apples.mysite.com bananas.mysite.com coconuts.mysite.com etc ... all of which point to webapps/fruit (these are hosts with a "/" context pointing to "webapps/fruit" as the docBase, to be more precise). When someone visits apples.mysite.com they see an apple, when they visit bananas.mysite.com they see a banana, and so on. Where in the fruit app is the best place for instance of Fruit to introspect itself (basically look for what host name it is defined under) and prepare accordingly? I've looked into using Context Parameters in the server.xml declarations but I would like to avoid this if possible b/c this functionally is more elegantly determined through introspection (the web-app saying "what host do i belong to?"). Of course I could always call request.getLocalName(), but that would be inefficient as it would have to be invoked on every request. I guess what I'm looking for someplace in the context initialization process where i could hook into and do my stuff and have it apply to the entire context throughout it's lifecycle. Can't seem to find it digging around the javax.servlet.* javadocs. thanks
