asp防止刷新，代码如下:
Sub chkreflash()
dim ScriptName
ScriptName=lcase(request.ServerVariables("PATH_INFO"))
dim posttime,DoReflashPage,ReflashPage,SplitReflashPage
posttime=1 '防止刷新时间
DoReflashPage=false
ReflashPage="|Article_one.asp"
SplitReflashPage=split(ReflashPage,"|")
for i=0 to ubound(SplitReflashPage)
if instr(scriptname,SplitReflashPage(i))>0 then
DoReflashPage=true
exit for
end if
next
if (not isnull(session("ReflashTime"))) and posttime>0 and DoReflashPage then
if DateDiff("s",session("ReflashTime"),Now())<posttime then
call msg("警告！系统已记录您的IP，和刷新次数。\n\n请不要在"&posttime&"秒内连续刷新本页面！","-1")
else
session("ReflashTime")=Now()
end if
elseif isnull(session("ReflashTime")) and posttime>0 and DoReflashPage then
Session("ReflashTime")=Now()
end if
End Sub

调用方法在页面首部加入chkreflash即可
