etax 2010[0] 1.fails to properly check the remote https server has a valid certificate for the host it claims to be from. Test case: edit the hosts file like this: IP_OF_HTTPS_SERVER_HERE etaxservices10.etax.ato.gov.au e.g. 203.0.178.114 (note: you need a certificate for _any_ domain signed by a CA installed on the client boxen). 2. will communicate over http if told to ;) (mod_rewrite etc.). ... etax 2010 will send the details of the tax request in a SOAP request. Have fun ;) [0] http://www.ato.gov.au/individuals/content.asp?doc=/content/32234.htm&page=5 -- Small things make base men proud. -- William Shakespeare, "Henry VI"
