OK, bohuzel je to v PHP, ja bych potreboval v ASP, ted jsem nasel
ze to jde i oklikou bez toho headeru napr. takto:

Low Tech Techique
A simple technique that requires no memorization of Header() information is to 
append a random number to the query-string of every URL you do not want 
cached. This is a technique that Yahoo uses.

V ASP by to mohlo byt asi tak (vyzkousim to):


<% Response.CacheControl = "no-cache" %>
<% Response.AddHeader "Pragma", "no-cache" %>
<% Response.CacheControl = "no-cache" %>
<% Response.AddHeader "Pragma", "no-cache" %>
<% Response.Expires = -1 %>
