I have a problem in the sense i need to display the right information in one post to the server.the problem is i need to cater for old versions of browsers.Included in my problem is i can only use the right frame in a 2 frame setup. An e.g. of what i am talking about is I have many Organisations & each one has Many Employees. Now i need a quick way (one post) to "navigate" to a particular employee in an organisation in one post.i may have over 50 000 employees so i do not want to post all the data down in one go and let the browser do some client-side sorting either.please could someone help me.
