Web Debugging Proxy:Fiddler

Fiddler是一款WEB調試代理工具.能檢視很多詳細的資訊.

Fiddler(http://www.fiddler2.com/fiddler2/),能把你目前的電腦和網際網路的所有HTTP,HTTPS的資訊.

允許你監視每個通訊和設定斷點.包括Internet Explorer, Mozilla Firefox, Opera等多種浏覽器.

http://localhost:8080/MYWEB/這種url的時候是不會被監視的,如果先監視本地網站,可以把localhost改為自己的機器的IP位址.

具體的很多東西,這個工具的一個統計片段例子:
