Hi,

Sometimes I encountered this phenomenon when browsing through the net:

In sample1.htm there is a link <a href='http://www.xxx.com/xxx/abc.asp?id_1=123&id_2=456'> . If I click this link from the page, I can get the query result I want. But if I copy this link and paste it back to the browser's address bar and press enter, it will bring me back to the homepage. How can this happen?

Thanks!
