異步請(qǐng)求類

作者：吾非無(wú)心
創(chuàng)建時(shí)間：2009.2
---------------------------------------------------------------------------------------------------------------------------------

修改記錄：

2009.4.27——添加 URL 檢測(cè)功能，如果是“http：//xxxx.xxx.xx.xx/..”這樣的格式，使用系統(tǒng)提供的“/getUrl.aspx”進(jìn)行獲取
以解決跨域問(wèn)題。
getUrl.aspx 的主要參數(shù)有兩個(gè)：1、url 值為目標(biāo)URL（URL中可以帶參數(shù)）——必須；2、method 值為代理使用的方法（可選）
如果method為空，默認(rèn)采用POST方法進(jìn)行代理；如果FORM參數(shù)為空（即request.content-length=0），則自動(dòng)設(shè)置為GET方法；
（注：getUrl.aspx在2009.4.27重新進(jìn)行了設(shè)計(jì)，在原完成代理的基礎(chǔ)上，新增了Cookie代理）
