Is there an https free test site available that I can use to test calling https SOAP webservices (using php5 soapClient object by the way) so that I can see what the impact is of having or not having correctly installed the certificate?
So far, I tried calling SOAP webservices like the ones mentioned in https://uk.ewaypayments.com/hotpotato/soap.asmx?WSDL or https://www.eway.com.au/gateway/rebill/test/manageRebill_test.asmx?WSDL, but I guess I am missing something or that certificates are installed automatically already in the browsers I used (IE9 and Chrome), because I did not have to do any certificate stuff.
