The Webtop admin guide says, both POST and GET methods are allowed. So theoretically they say both POST and GET methods should work. All the cgi scripts there are using the GET method, but I'm not able to argue that I can't use POST method until I can prove that
This is the link to the admin guide for Webtop server. Its a 5 MB file. (http://publib.boulder.ibm.com/infocenter/tivihelp/v8r1/topic/com.ibm.netcool_wt.doc/ag/Administration_Guide.pdf) . In chapter 10, Administering Tools, it says I can use both POST and GET methods.
