what is the best method of hiding the file name in the URL from a developers side (who has no control over the server), for example if the site is www.123.co.za/contact.htm - i wan the user to only see www.123.co.za. an example of such can be seen here http://www.groupon.co.za
ways i know of is using one page and dynamically loading page content using ajax the other is frames
(诸如变式-重饰式i器作为一机可进入或控制服务器的服务器)
