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);
Apache2::ConnectionUtil provides the following functions and/or
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();
$key( string )
A key value
$val( SCALAR )
Any scalar value (e.g. a reference to an array)
$val are passed the previous value for
returned if such existed, otherwise undef is returned.
$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
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
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
