Hi, I'm confused/puzzled by how LWP handles URI escapes vs. URI::Escape. Say I have a form parameter named "data" with value "12 34+56".

use strict;
use URI::Escape:
use LWP:Simple;

my $res = get("http://www.foo.com?data=".uri_escape("12 34+56")); #sen
+t as: data=12%2034%2B12, both space and "+" are escaped.
my $res2 = get("http://www.foo.com?data=12 34+56")); # sent as: date=1
+2%2034+56, i.e. space is escaped, but "+" is not.

I was expecting get() to also escape "+" for me. After stepping through the code, I see that LWP::Simple::get() does call something like uri_escape:

# in URI::_init(C:/Perl/site/lib/URI.pm:76):
  $str =~ s/([^$uric\#])/$URI::Escape::escapes{$1}/go;
# where $uric is:
# \;\/\?\:\@\&\=\+\$\,\[\]A-Za-z0-9\-_\.\!\~\*\'\(\)%

where you can see "+" is not escaped, plus a few others. URI::Escape::uri_escape is implemented as:

    $text =~ s/([^A-Za-z0-9\-_.!~*'()])/$escapes{$1}/g;

which would escape "+". My question is why URI::Escape is escaping more than what get() does (via URI::_init)? or why get() doesn't do the "appropriate" escaping? is the best practice to escape everything before sending to get() rather than relying on its escaping? how about UserAgent::post? will it escape its values completely? or am I missing something? Thanks.
