I'm building a website using Zend Framework and having trouble implementing modules and custom routes.
There are basically two rules:

• Select a module based on the domain (multiple domains can select a single module)
• Regardless of domain, select one specific module based on path

Examples:

• domain1.com selects module domain1
• domain1.net selects module domain1
• domain2.com selects module domain2
• both domain1.com/admin and domain2.com/admin select module admin

This is the first project where I use ZF, so my experience with the framework is basically non-existent. I have done some dirty hacking in my bootstrapper where I check the domain and than execute Zend_Layout::startMVC() to get the correct layout, but that is messed up when I'm implementing custom routes.

So I was wondering what is the best way to go about implementing this?
