Hi All,
I would like to thank all who tried to help, i was finally able to
solve the problem by:
1. Install all 3 FlexBuilder hotfixes.
2. Add the following http headers:
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Pragma: private');
In two places:
a. In a php script which returns the WSDL file (see code below).
b. In the service method which handles the WS calls, i was using PHP
as server side language and the headers should be set right before we
return the result object (inside the class which handles the WS
method) and not in the service PHP script which creates the PHP
SoapServer object.
Thanks,
Eyal

that the player converts POSTs with an empty body to GETs
automatically (which is probably due to bugs in the underlying ActiveX
or Netscape Plugin APIs).
