Not at all, I have no idea what they are, and ignorance is bliss! Ah... Blessed ignorance...

$r-subprocess_env('REQUEST_URI') returns undef ?
From:
http://perl.apache.org/docs/2.0/api/Apache2/RequestRec.html#C_subprocess_env_
subprocess_env
Get/set the Apache subprocess_env table, or optionally set the value of
a named entry.
When the $key argument (string) is passed, it returns the corresponding
value (if such exists, or undef. The following two lines are equivalent:
$val = $r-subprocess_env($key);
$val = $r-subprocess_env-get($key);
Ok... Seems simple enough...
In my module if I do the following:
$r-subprocess_env;
my $uri = $ENV{REQUEST_URI};
The I get the URI.
But if I change the above to:
my $uri = $r-subprocess_env('REQUEST_URI');
I get undef.
Confused.

RE: $r-subprocess_env('REQUEST_URI') returns undef ?
At the risk of being kind of obvious, did you try $r-uri?

Tosh, do you know what VOID context means in perl?
@list=function() # this list context
$scalar=function()# this is scalar context
function()# this is void context: the return value is ignored
Now, in void context and only then subprocess_env() calls
ap_add_common_vars(r);
ap_add_cgi_vars(r);
These 2 functions add such things like REQUEST_URI to the environment.
So, if you do it like this:
$r-subprocess_env; # void context
my $uri = $r-subprocess_env('REQUEST_URI');
it is very likely that you get the REQUEST_URI.
But as David pointed out, $r-uri is the much better way.

Re: $r-subprocess_env('REQUEST_URI') returns undef ?
It's probably obvious, but $r kinda scares me. I guess I saw
subprocess_env in the docs and so that's where I stopped... What a
couple centimeters more would have done...
Thank-you David!!

Re: $r-subprocess_env('REQUEST_URI') returns undef ?
Ah... I assumed that $r-subprocess_env in VOID context was an expensive
operation as it populated $ENV (from what I had read) as one should try
to avoid it. I also find it non-intuitive that:
$r-subprocess_env; # void context
my $uri = $r-subprocess_env('REQUEST_URI');
is the same as
$r-subprocess_env;
my $uri = $ENV{REQUEST_URI};
But that's obviously just my lack of intuitiveness.
Yes, $r-uri is about a billion times more useful, thank-you again
David, and thanks for your help Torsten!
