First you can setup aliases in the Host, something like <Host name="mysite.com" appBase="fruit-webapps"> <Alias>apples.mysite.com</Alias> <Alias>bananas.mysite.com</Alias> <Alias>coconuts.mysite.com</Alias> </Host> Then install your webapp into "fruit-webapps/ROOT.war". > 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? In this setup there is only one webapp, so it cannot be done per webapp context, or even per servlet instance. > Of course I could always call request.getLocalName(), but that would be > inefficient as it would have to be invoked on every request. I check request.getServerName() in the main index.gsp (it's a Grails app) and then put the result into the session. If you don't use sessions and have more than one servlet, I guess you can do the check in a filter. I don't think it's that inefficient.
