Did you actually read the documentation that was suggested to you in
the previous replies?

>>From `perldoc Data::Dumper` :
Given a list of scalars or reference variables, writes out
their contents in perl syntax. The references can also be
objects. The contents of each variable is output in a
single Perl statement. Handles self-referential structures
correctly.

The return value can be "eval"ed to get back an identical
copy of the original reference structure.

So, if you have

my $saved = Dumper(\%ReallyBigStruct);

and you've sent $saved through your socket, you can get back to your
data by doing:

my $restored = eval $saved;
my %CopyOfReallyBigStruct = %$restored;

(Or, if you want to skip the temp variable...)

my %CopyOfReallyBigStruct = %{eval $saved};
