Hi Akhilesh,<BR>Your article about "disabling the Back Button" is very good on the normal case. But if there is a cearch list box on the firstTimeToPage.asp, if I search a data from list box then submit to same FirstTimeToPage.asp(i.e., action=firstTimeToPage.asp)let some contents display. The displayed data link to the somepage.asp, after I click this link to somepage.asp, then click the back button of the browser, The Data missing page still display. For this case. How to sovle! Thank you.
