When the user clicks on a link, I need to get some saved values from database. If the number of saved values is equal to 10
then a pop up will be opened which will display all those saved values and there will be a delete link corresponding to each
saved value. If the user clicks on any delete link that particular value will be deleted from the database and the same popup
will be displayed with 9 values. If the max is not reached then some other page will be displayed in the same window (no pop up in this case), this page will allow the user to save some values. This process will go on till the max is reached (in that case pop up comes)
But I have realised some problem. If the same user logs in from 2 differnet machines, then there wil be a problem (user may be able to save more than the maximum allowed).
Please let me know how should I go about it.
