函数getcache,会自动建立需要的缓存。 复制代码 代码如下: Function getcache(funsname,isreset,isarr,timeinfo) ‘funsname — 需要缓存的内容,这里要输入一个function名 ‘isreset –是否更新[值:0(根据时间或判断缓存为空时自动更新)、1(主动更新)] ‘ isarr —- 所缓存的内容是否为一个数据[0为字符串,1为数组] ‘ timeinfo —- 缓存更新时间,单位为秒,当值为0时,则只在缓存为空时,才更新 dim domain = “cnzhaopin.com.cn” Dim temp_getconfig Dim re_getcache : re_getcache = False Dim temp_isarray_type : temp_isarray_type = False Dim Appfunsname : Appfunsname = Replace(Replace(Replace(funsname,”(”,”"),”)”,”"),”,”,”.”) If isarr = 1 Then temp_isarray_type = True If isreset = 1 Then re_getcache = True If isreset = 2 Then execute(”temp_getconfig=”&funsname) getcache = temp_getconfig Exit Function End If If Application(domain&”_”&Appfunsname&”_time”) = “” And timeinfo<>0 Then re_getcache = True If Not re_getcache Then If temp_isarray_type Then If Not IsArray(Application(domain&”_”&Appfunsname)) Then re_getcache = True Else If Application(domain&”_”&Appfunsname) = “” Then re_getcache = True End If End If If Not re_getcache And timeinfo<>0 Then If Int(DateDiff(”s”,Application(domain&”_”&Appfunsname&”_time”),now()))>timeinfo Then re_getcache = True End If If re_getcache Then execute(”temp_getconfig=”&funsname) Application.Lock Application(domain&”_”&Appfunsname) = temp_getconfig Application(domain&”_”&Appfunsname&”_time”) = Now() Application.UnLock Else temp_getconfig=Application(domain&”_”&Appfunsname) End If getcache = temp_getconfig End Function 使用时: 复制代码 代码如下: Function output3 output3=”" set newrs=conn.execute(”select TOP 60 companyname,comid,vipdata,ishot from company where isok=1 and vipqx>60 and vipqx<300 and vip=1 and comid in (select comid from jobs where zt<>1) order by newid()”) do while not newrs.eof output3=output3 & “……….” newrs.movenext loop newrs.close set newrs=nothing End function response.write getcache(”output3″,0,0,3600) |
