Symfony Environment and Debug Panel

I am new to symfony. I did some tests (Symfony 2.0.13 with php5.3.8 in WAMP2.2) and read, but I'm a little confused with the environments.

When I go to LOCALHOST/Symfony/web/app_dev.php/demo/hello/Foo(app_dev means development environment, right?) I see the web debugging toolbar and clicking the profiler information on the Project Configuration tab, I see: Environment

Now I go to LOCALHOST/Symfony/web/app.php/demo/hello/Fooand in the web debugging toolbar (BTW, why am I seeing this toolbar now? Is it not a production environment? Can my users see this bar by default?) I also see, on the "Project Configuration" tab: Environment

It seems that this "demo" bundle is somehow related to "dev", regardless of which url is app_dev.php or app.php ??

In addition, I did some more tests: my local IP address is 192.168.153.1.

When I try to access:

http://192.168.153.1/Symfony/web/app_dev.php/demo/hello/Foo

he says: "You are not allowed access to this file. For more information, check app_dev.php." So, well, if I edited the lines in app_dev.php and added my (external) IP address, I could access it.

BUT when I connect to

http://192.168.153.1/Symfony/web/app.php/demo/hello/Foo

IT SAYS THE SAME! It looks like my app.php is not running, and the app_dev.php application is running no matter what I type in the URL.

This is really confusing! I checked my htaccess and everything seems to be correct.

Can someone help me figure this out?

app_dev.php app.php, " " .
