Who gets which request?
I have a Tomcat 7.0.16 install with two WAR based webapps in it.
First test case:
Two war files in <tomcat-home>/webapps at startup
1. ROOT.war
2. another.war
If I request http://localhost:8080/another/something it goes to the
another webapp.
Second test case:
Two war files in <tomcat-home>/webapps at startup
1. ROOT.war
2. wibble.war
If I request http://localhost:8080/wibble/something it goes to the ROOT
webapp.
Third test case:
One war file in <tomcat-home>/webapps at startup
1. ROOT.war
Second war file added to <tomcat-home>/webapps after startup (with
auto-deploy on)
2. another.war
If I request http://localhost:8080/another/something it goes to the ROOT
webapp.
It looks like Tomcat is adding the webapps contexts to it's "filter"
list in alphabetical order at startup and then adding any auto-deployed
WARs afterwards but I can't believe it is that simple. Can anyone
give/link to a proper explanation?
Cheers

That isn't right. Looks like wibble.war failed to deploy.

Requests are mapped to contexts based on the longest matching context
path (as per the Servlets spec).
You can use the Manager app to see if apps have deployed and are started.

That is the expected behaviour.

That does not look normal.
But, how do you *really* know that it /goes to/ the ROOT webapp ?
Can you provide some details ?

That does not look normal either.
