SOAP::Constants(3) User Contributed Perl Documentation SOAP::Constants(3)NAMESOAP::Constants - SOAP::Lite provides several variables to allows
programmers and users to modify the behavior of SOAP::Lite in specific
ways.
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 governed.
CONSTANTS
$DO_NOT_USE_XML_PARSER
The SOAP::Lite package attempts to locate and use the 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 this value to 1, there will be no
attempt to locate or use XML::Parser. There are several reasons you
might choose to do this. If the package will never be made available,
there is no reason to perform the test. Setting this parameter is less
time-consuming than the test for the package would be. Also, the
XML::Parser code links against the Expat libraries for the C language.
In some environments, this could cause a problem when mixed with other
applications that may be linked against a different version of the same
libraries. This was once the case with certain combinations of Apache,
mod_perl and XML::Parser.
$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 header, however. If dealing with an
endpoint that expects to do a more literal examination of the header as
whole (as opposed to fully parsing it), this parameter may prove
useful.
$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, and badly coded endpoints
might send valid messages with invalid Content-Type headers. While the
"right" thing to do would be to reject such messages, that isn't always
an option. Setting this parameter to 1 allows the toolkit to skip the
content-type test.
$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;
