Thanks for the example.
It seems with ZF 1.9.1 I can do just this:

$hostnameRoute = new Zend_Controller_Router_Route_Hostname(
‘:username.domain.com’,
array(
‘module’ => ‘default’,
‘controller’ => ‘index’,
‘action’ => ‘index’,
),
array(’username’ => ‘(?!www$).*’) // skip www as a username
);

$router->addRoute(’user_route’, $hostnameRoute);

I’m writing an application that heavily logs all activity. Do you think it’s advisable to modify this session code to serve as a logging system? Ultimately, we want to track every action by every visitor.

Thanks again,
David

and I strongly recommend to setup separate virtual host in your apache for each new site, portbased is just fine for development. So you will access it on:
http://localhost:8888/user/register
for example

I am accessing like this:

http://localhost/part4/user/register

correct the above url to get the form.

have you tried the fixed code, I have posted?

I wonder if the goose’s problem is solveed or not, because I encountered the same error. I think the problem comes from the interaction between zend_auth and zend_session, but how to sovle it?
