Headers with multiple arguments

[Christopher Lewis <clewis@myfonts.com>]

Hi again,

I've been experiencing an anomaly with PEAR::SOAP where SOAP header method calls are treated differently than the same-formatted method calls in the SOAP body.  The Server.php header processing turns multiple arguments into a single Struct variable on the server side.  For instance, this header:

<SOAP-ENV:Header>
<ns4:requestSessionID SOAP-ENV:actor="http://schemas.xmlsoap.org/soap/actor/next";
SOAP-ENV:mustUnderstand="1">
<clientKey xsi:type="xsd:string">christester</clientKey>
<userAgent xsi:type="xsd:string">...user agent string...</userAgent>
</ns4:requestSessionIDwithUserAgent>
</SOAP-ENV:Header>


My SOAP server header method is reading this as a single struct argument with "clientKey" and "userAgent" keys, rather than two separate arguments.  Body methods separate the arguments the way I would expect.

I changed this behaviour by changing "_decode" to "__decodeRequest" on line 333 of Server.php, analogous to the way the body method arguments are processed.  Is this actually an appropriate fix?
