Response.Expiresabsolute = Now() - 1
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"

这一段主要功能就是让网页不缓冲,防止页面重复提交
Response.Expires = 0 '强迫缓存页到期
Response.Expiresabsolute = Now() - 1 '指定页面缓存的失效时间
'不要网页存于缓存之中
Response.AddHeader "pragma","no-cache"
Response.AddHeader "cache-control","private"
Response.CacheControl = "no-cache"
