6 SOAP::Constants - SOAP::Lite provides several variables to allows
7 programmers and users to modify the behavior of SOAP::Lite in specific
8 ways.
9
11 A number of "constant" values are provided by means of this namespace.
12 The values aren't constants in the strictest sense; the purpose of the
13 values detailed here is to allow the application to change them if it
14 desires to alter the specific behavior governed.

17 $DO_NOT_USE_XML_PARSER
18 The SOAP::Lite package attempts to locate and use the XML::Parser
19 package, falling back on an internal, pure-Perl parser in its absence.
20 This package is a fast parser, based on the Expat parser developed by
21 James Clark. If the application sets this value to 1, there will be no
22 attempt to locate or use XML::Parser. There are several reasons you
23 might choose to do this. If the package will never be made available,
24 there is no reason to perform the test. Setting this parameter is less
25 time-consuming than the test for the package would be. Also, the
26 XML::Parser code links against the Expat libraries for the C language.
27 In some environments, this could cause a problem when mixed with other
28 applications that may be linked against a different version of the same
29 libraries. This was once the case with certain combinations of Apache,
30 mod_perl and XML::Parser.
31 $DO_NOT_USE_CHARSET
33 Unless this parameter is set to 1, outgoing Content-Type headers will
34 include specification of the character set used in encoding the message
35 itself. Not all endpoints (client or server) may be able to properly
36 deal with that data on the content header, however. If dealing with an
37 endpoint that expects to do a more literal examination of the header as
38 whole (as opposed to fully parsing it), this parameter may prove
39 useful.
40 $DO_NOT_CHECK_CONTENT_TYPE
42 The content-type itself for a SOAP message is rather clearly defined,
43 and in most cases, an application would have no reason to disable the
44 testing of that header. This having been said, the content-type for
45 SOAP 1.2 is still only a recommended draft, and badly coded endpoints
46 might send valid messages with invalid Content-Type headers. While the
47 "right" thing to do would be to reject such messages, that isn't always
48 an option. Setting this parameter to 1 allows the toolkit to skip the
49 content-type test.
50 $PATCH_HTTP_KEEPALIVE
52 SOAP::Lite's HTTP Transport module attempts to provide a simple patch
53 to LWP::Protocol to enable HTTP Keep Alive. By default, this patch is
54 turned off, if however you would like to turn on the experimental patch
55 change the constant like so:
56 $SOAP::Constants::PATCH_HTTP_KEEPALIVE = 1;
