=head1 NAME

SOAP::Constants - SOAP::Lite provides several variables to allows programmers and users to modify the behavior of SOAP::Lite in specific ways.

=head1 DESCRIPTION

A number of "constant" values are provided by means of this namespace. The values aren't constants in the strictest sense; the purpose of the values detailed here is to allow the application to change them if it desires to alter the specific behavior...

=head1 CONSTANTS

=head2 $DO_NOT_USE_XML_PARSER

The SOAP::Lite package attempts to locate and use the L<XML::Parser> package, falling back on an internal, pure-Perl parser in its absence. This package is a fast parser, based on the Expat parser developed by James Clark. If the application sets thi...

=head2 $DO_NOT_USE_CHARSET

Unless this parameter is set to 1, outgoing Content-Type headers will include specification of the character set used in encoding the message itself. Not all endpoints (client or server) may be able to properly deal with that data on the content head...

=head2 $DO_NOT_CHECK_CONTENT_TYPE

The content-type itself for a SOAP message is rather clearly defined, and in most cases, an application would have no reason to disable the testing of that header. This having been said, the content-type for SOAP 1.2 is still only a recommended draft...

=head2 $PATCH_HTTP_KEEPALIVE

SOAP::Lite's HTTP Transport module attempts to provide a simple patch to
LWP::Protocol to enable HTTP Keep Alive. By default, this patch is turned
off, if however you would like to turn on the experimental patch change the
constant like so:

  $SOAP::Constants::PATCH_HTTP_KEEPALIVE = 1;
