推薦：如何提高asp程序訪問(wèn)速度
用asp程序進(jìn)行網(wǎng)頁(yè)設(shè)計(jì)，大多因?yàn)樾枰L問(wèn)數(shù)據(jù)庫(kù)，然后再將數(shù)據(jù)顯示到頁(yè)面，如果數(shù)據(jù)很多的話，頁(yè)面的訪問(wèn)速度也就變慢了，為了解決這個(gè)問(wèn)題，可以用以下技巧來(lái)提高頁(yè)面訪問(wèn)速度。技巧之一：提高使用Request集合的效率訪問(wèn)一個(gè)ASP集合來(lái)提取一個(gè)值是費(fèi)時(shí)的

小寫數(shù)字轉(zhuǎn)大寫

分享：詳解ASP的Session對(duì)象
一、屬性 1、SessionID SessionID屬性返回用戶的會(huì)話標(biāo)識(shí)。在創(chuàng)建會(huì)話時(shí)，服務(wù)器會(huì)為每一個(gè)會(huì)話生成一個(gè)單獨(dú)的標(biāo)識(shí)。會(huì)話標(biāo)識(shí)以長(zhǎng)整形數(shù)據(jù)類型返回。在很多情況下SessionID可以用于WEB頁(yè)面注冊(cè)統(tǒng)計(jì)。 2、TimeOut Timeout屬性以分鐘為單位為該應(yīng)用程序的Sessi
