query not refreshing data

query not refreshing data

hi
 
i have setup a rest service that is exposing some data via get.
 
i can consume the service with jquery and show it on a html page.
 
my problem is the data does not refresh. to get the current data i have to close all browser tabs and reopen.
 
scenario :
1 - wcf exposes a 3 records
2 - jquery html client web page consumes the service and shows the 3 records , working on workstation 1
3 - add one extra record from workstation 2
4 - on workstation 1 if i refresh nothing happens.....i have to close all browser tabs and reopen the page.
 
any ideias what im missing ?
 
thks in advanced
