<br>1.  可以手工输入HTTP��h���Q��ƈ向服务器发送�?<br>
<br>2.  接收服务器的响应消息�?<br>
<br>3.  消息头和实体内容分段昄����Q�也���是��_���q�不是象Telnet�{�客��L��一样将HTTP�?<br>
<br>应消息全部显�C�，而是先显�C�消息头�Q�然后由用户军_��是否昄���实体内容�?<br>
<br>4.  集中发送请求。这个HTTP模拟器和Telnet不同的是�Q��ƈ不是一开始就�q�接服务器，而是���域名、端口以及HTTP��h��消息都输完后�Q�才�q�接服务器，�q�将�q�些��h��发送给服务器。这样做的可以预防服务器提前关闭�|�络�q�接的现象�?<br>
