use Apache2::Connection (); use Apache2::ConnectionUtil (); use Apache2::RequestRec (); # grab the connection object; my $c = $r->connection; # share perl objects like $r->pnotes $old_val = $c->pnotes($key => $value);
pnotes
Share Perl variables between requests over the lifetime of the connection.
$old_val = $c->pnotes($key => $val); $val = $c->pnotes($key); $hash_ref = $c->pnotes();
$c
( Apache2::Connection object
)
$key
( string )
A key value
$val
( SCALAR )
Any scalar value (e.g. a reference to an array)
if both, $key
and $val
are passed the previous value for $key
is
returned if such existed, otherwise undef is returned.
if only $key
is passed, the current value for the given key is returned.
if no arguments are passed, a hash reference is returned, which can then
be directly accessed without going through the pnotes()
interface.
See
(Apache2::RequestUtil::pnotes
)
for the details of the pnotes
method usage. The usage is identical
except for a few differences. First is the use of $c
instead of
$r
as
the invocant. The second is that the the data persists for the lifetime of
the connection instead of the lifetime of the request. If the connection is
lost, so is the data stored in pnotes
.
