Why need it? For the same reason that java servlets have Filters...because
it's a heck of a lot easier to be able to route all requests through
interceptors that handle specific functionality. For example, authentication
handling. i'd rather have an AuthFilter (or comparable functionality in a
coldfusion Application.cfm file) through which every request runs that
contains all the logic for ensuring a user is logged in and, if not, routed
to the appropriate page. Seems to me that if I want this type of
functionality in PHP, I have to have an include at the top of each page.
For this rinky dink site i'm doing this quick work for, it's not a big
deal..... just annoying and time wasting IMHO.

it's not localhost because i have dozens of other sites on this machine,
with each site as a subdirectory under the root. never thought of using
hosts file before.

that one didn't work for me. my normal doc root for all coldfusion
development is in my cfusionmx\wwwroot directory, and that's the site that's
configured as the base in IIS. but for this php stuff, i've got everything
in inetpub\wwwroot, and have virtual directories set up for it. but
Document_Root is returning the cfusionmx\wwwroot directory. good thought
though!

Tell me about it brother. I'm so used to java and coldfusion cfcs that
coming back to regular old scripting is very foreign.
i've found php remarkably simple to learn, especially thanks to the
incredible documentation. it's just one or two things i'm coming across that
are slipping me up.
