receiving XML by POST

[Maarten Stolte <da...@crash.nu>]

Hello,

i'm trying to figure out how to receive an xml message/file/stream(?)
using POST, and how to be able to then send that to somewhere else
(DBI).
We're using MASON, don't know if that is information needed in this, but
i saw something about MASON picking up all posts.

Mason generally does an automatic read of POST data, specify what form
fields you want, and it'll stuff the values into variables named the same
as the name fields in the POST data.   You should just be able to have the
XML be the value for some name/value pair, then do all your XML
parsing/DBI work on that value.

I believe the usual way to access POST data, $r->content, is only
for form data.  To get XML data, try this:

  my $buf = '';
  $r->read($buf, $ENV{CONTENT_LENGTH});

This is a general mod_perl API issue, and not necessarily specific
to Mason, though Mason may have some other API specific to this.
This may in fact collide with Mason form processing if there is
any, since a mod_perl application will hang if it tries to 
read the POST data twice.
