[XML-SIG] GET vs POST (was WSDL library ?)

Not quite 'synonymous'': GET Options are stored in an environmentvariable QUERY_STRING by 
the server before calling the cgi program. Environment variables mostly have a limited length.
With POST the CGI has to read the standard input. That stream can be much much longer than 
QUERY_STRING. 

Using POST is safer because you don't need to know which operating system the web server 
runs on.
