I have a perl script, and I want to retrieve the method used to make the HTTP Request that caused this Perl script to execute.

It seems to me like the following bit of code would do it:
my $method = $r->method();

This code is described in:
http://perl.apache.org/docs/2.0/api/Apache2/RequestRec.html#C_method_

However, my problem is (as a bit of an Apache Server, and Perl newb), that it does not describe how to get the $r variable, which seems to be an instance of Apache2::RequestRec. Do I retrieve it from somewhere, is it passed into my program, or do I have to instantiate it?

Any help would be appreciated.

# Objects are a trip .. harder to explain than understand for me.

# $r->method() returns a value, $r is a pointer to the object
# so in the example you linked to, $method is equal the value returned by $r->method()
# thier use of $method could be confusing, so we'll change it.

# what's the current request (GET/POST/etc)?
$myvalue= $r->method();

# $myvalue is now going to contain either "GET", "POST", "HEAD", "WHATEVER"
# if form content was posted, $myvalue is going to = "POST"

# If the current method is set to POST, and you now set it to GET
$myvalue = $r->method("GET");

# the docs state that it returns the prior setting so $myvalue is going to = "POST" still.

# Let's now change it to HEAD.

$myvalue = $r->method("HEAD");
# $myvalue is going to = "GET", the prior setting.

$myvalue = $r->method();
# $myvalue is going to = "HEAD" the current setting.
