Wildcard subdomain priority for Google AppEngine - google-app-engine

Question

I want to use the functionality of dispatch.xml to route my request by subdomain and create a default module which will receive all the non specified subdomain.
I explain myself:
Let's say I have 3 differents modules:
Module 1 routed from: m1.myapp.com
Module 2 routed from: m2.myapp,com
Default Module routed from anything else: *.myapp.com (like: default.myapp.com, *entitieName*.myapp.com, other.myapp.com).
My question: is there any kind of priority mechanism that will handle first written subdomain and if and only if the subdomain called isn't in the dispatch.xml it will route the request to my default module?

Answer 1

Yes, you already have such priority mechanism - that's exactly how dispatch.xml works:
the order of the dispatch rules matter, the first pattern match wins and the request will be dispatched according to that rule
if none of the rules matches the request will be sent to the default service/module.
Something along these lines should do what you desire:
<?xml version="1.0" encoding="UTF-8"?>
<dispatch-entries>
<dispatch>
<url>m1.myapp.com/*</url>
<module>m1</module>
</dispatch>
<dispatch>
<url>m2.myapp.com/*</url>
<module>m2</module>
</dispatch>
</dispatch-entries>
