I get an error when trying to print some of my asp pages or when I try and use the back button. Here is the error:<BR><BR><BR>Data Missing<BR><BR>This document resulted from a POST operation and has expired from the cache. If you wish you can repost the form data to recreate the document by pressing the reload button.<BR><BR><BR>This error only seems to take place on the post method. I have exhuasted all of my resources and still I have no answer. I have this line of code at the top of all my pages:<BR><BR>&#060;%@ Language=VBScript %&#062;<BR>&#060;% Option Explicit %&#062;<BR>&#060;% response.buffer = "true" %&#062;<BR><BR>I have now tried using the below with the above, but still I get the error:<BR><BR>&#060;%<BR>response.expires = 600<BR>Response.AddHeader "cache-control", "store"<BR>Response.AddHeader "pragma", "cache"<BR>%&#062;<BR>&#060;META HTTP-EQUIV="EXPIRES" CONTENT="0"&#062;<BR><BR><BR>Anyone have any ideas of how to fix this error?<BR><BR>Thanks A Lot,<BR> Eric<BR>
