This was done to avoid user seeing anything on the site once he has logged off.<BR><BR>Response.AddHeader "pragma","no-cache" <BR>Response.AddHeader "cache-control","private" <BR>Response.CacheControl = "no-cache" <BR>response.buffer =true<BR><BR>This is working fine only for one major problem. wherever i submit a value from a form and when i get the result if i go back it shows me as page has expired and shows the foll error<BR><BR>"As a security precaution, Internet Explorer does not automatically resubmit your information for you. "<BR><BR>Wonder why this is happening and this happens only when i am getting the value from a form.<BR><BR>Can some one help me on this<BR><BR><BR>
