[mp2] a way to map a uri to a physical path

[Foo JH]

Hi all,

I'm trying to find the class/ method which allows me to get the physical
path base on the uri. Something similar to Server.MapPath('/index.htm')
in ASP.NET.

Any advise is appreciated. Thanks.

$r-document_root . $r-uri

but that won't actually tell you if that file exists, it's just where
you'd probably expect that file to reside.  Not having any idea how that
ASP.NET function works, i don't know if that really answers your
question or not.

Thanks for replying. In my case it's a wee bit more complicated (forgot
to mention).

Thing is, I have alias-ed a path (eg. alias /thisuri c:/wwwroot) in the
web server, so $r-uri may not point to the right location.

Is there a generic method so that given any uri as a parameter, the
library can do the math and return the physical path?

$r-filename by the looks of things.

I'm not sure if that's the one. From the docs (your ref link):

filename

Get/set the filename on disk corresponding to this response (the result
of the URI -- filename translation).

Sounds like this method assigns a file to the uri instead.

If you look for the filename for $r-uri, that means the uri of the 
current request then $r-filename holds that after the map-to-storage 
phase.

If you need a general method to map an arbitrary URI to a filename then 
it is a subrequest:

  my $subr=$r-lookup_uri($uri);
  if( $subr-status == Apache2::Const::OK and
  -f $subr-filename ) {
$filename=$subr-filename;
  }

But keep in mind that it may result in quite unusual filenames if you 
use the mod_proxy handler for example. Also, the file may not exist. 
The status 404 is generated only in the response phase. Further, you 
must perhaps check $subr-path_info for being empty.
