GET or sometimes POST sounds worth exploring, but i'm not sure it's something i'd require.

This particular service was initially implemented as a CGI. The POST data contained the SOAP request which was passed onto a Mainframe service, the query string parameters contained routing and security parameters. The GET parameters usually remained static across each call - though URL re-writing could have been employed here. 

When the service was later migrated to a J2EE SOAP toolkit the abstraction caused the query string parameters to be unavailable in the bean.

How GET and POST may be safely combined in a HTTP/SOAP service is unclear (to me at least).

You mean (in WSDL terms), a single operation that exchanges messages 
sometimes with GET, sometimes with POST?

I don't think we have that flexibility today, but maybe this is 
something we should explore.
