There is no such a limit in Apache and probably most browsers. The limit
can be the amount of available RAM (if the file is aggregated in the
memory) or the filesystem limits (not enough disk space, if the uploaded
file is created on the filesystem). You can limit it within your code,
though.

Since CGI.pm is the base of Apache::Request (but written in Perl,
whereas Apache::Request is written mostly in C), parts of CGI.pm's
extensive documentation will apply for Apache::Request as well.
So if you look at CGI.pm's manpage you will see that it's in bytes:
$CGI::POST_MAX
If set to a non-negative integer, this variable puts a
ceiling on the size of POSTings, in *bytes*.
....If CGI.pm
detects a POST that is greater than the ceiling, it
will immediately exit with an error message. This
value will affect both ordinary POSTs and multipart
POSTs, meaning that it limits the maximum size of file
uploads as well. You should set this to a reasonably
high value, such as 1 megabyte.
You are welcome to send the documentation patches to the developers of
the Apache::Request package at [EMAIL PROTECTED] This kind of
contribution helps a lot.

either:
my $real_r = $r->is_main ? $r : $r->main;
my $apr = Apache::Request->new($real_r, POST_MAX => 1024);
or
$apr = Apache::Request->new( ($r->is_main ? $r : $r->main),
POST_MAX => 1024 );
