我在用j2me和android訪問我們自己的服務器時，如果選用cmwap連接是有時候會返回這樣的信息(抓包抓的)：
<?xml version="1.0"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "//www.wapforum.org/DTD/wml_1.1.xml">
<wml><card><p><do type="prev" name="Back" label="Back"><prev/></do>Not an error.  You should not be seeing this message.</p></card></wml>
在服務器的log中查(cha)看(kan)請求并沒有(you)發送到，也就(jiu)是(shi)說移動把請求攔截了(le)，但是(shi)有(you)時(shi)候會(hui)連接上

下邊(bian)是用移動卡(ka)和聯通卡(ka)訪問頁面Headers信息：

后來(lai)又(you)發現，移動卡(ka)若(ruo)改用(yong)cmnet接入(ru)代碼就能正(zheng)常獲取User-Agent，所以(yi)，中國移動cmwap上網攔截了手(shou)機User-Agent!
