This is our mistake, sorry for that. There was incorrect information about cache control in the WAP Service Developers Guide for Nokia Series 60 Phones with XHTML Browser v1.0 but this has been corrected to version 1.1. The fact is that the XHTML browser in Nokia Series 60 phones (Nokia 3650) does not support any form or attributes of the Meta element. So, the "no-cache" value of the Cache-Control attribute would have no effect. The usage of cache can be controlled by using HTTP headers. "no-cache" HTTP header directive can be set by the HTTP server hosting the pages.
