get:點(diǎn)擊網(wǎng)址，超鏈接，method后面寫get,查詢最大255字符，是以明文形式進(jìn)行傳輸?shù)?，傳輸不了中文（傳中文得處理，有的瀏覽器可能會(huì)自動(dòng)處理）。
post：method后面寫post，不是以明文的形式進(jìn)行傳輸，相對(duì)來(lái)說(shuō)安全，post傳輸?shù)臄?shù)據(jù)量沒有大小限制.
web應(yīng)用程序使用三層體系結(jié)構(gòu)

什么是 Servlet ?
Servlet 是一個(gè)java類，能運(yùn)行在服務(wù)器上，處理客戶端發(fā)送過來(lái)的請(qǐng)求（get,post）
servlet生命周期
servlet是以單例的模式完成的，構(gòu)造器調(diào)用一回。
init:只有在第一次訪問servlet 時(shí)調(diào)用初始化
service:有doget(),和dopost()方法
destory:結(jié)束服務(wù)器的時(shí)候調(diào)用
request 請(qǐng)求
response 響應(yīng)

數(shù)據(jù)庫(kù)連接池
提高我們的數(shù)據(jù)庫(kù)并發(fā)訪問能力，不能從根本上解決
假如支持1秒鐘100個(gè)并發(fā)訪問(最大并發(fā)訪問量)，先一直開30個(gè)連接(最大空閑數(shù))，有人訪問就給他，如果超過30個(gè)，就在開新的連接，如果超過100個(gè)，后面的排隊(duì)，等前面的連接用完。
Cookie
是存在于客戶端，瀏覽器所在的那塊硬盤上的一個(gè)文本文件，是以鍵值對(duì)（鍵值都是字符串）的形式存儲(chǔ)的
例如論壇記住密碼1周，1天都是存在COOkie里，在登錄的時(shí)候，在要求的時(shí)間里都自動(dòng)登錄
