老乡们，请问asp中如何获得这个url参数？

不太明白你的问题。
是不是这样：
<%
response.redirect "www.aaa.com/bbb/ccc"
%>

呵呵

用ASP的字符函数呀:

dim urlstr
urlstr="http://www.aaa.com/bbb/ccc/index.htm"
urlstr=Mid(urlstr,Len("http://"),Len(urlstr)-Len("index.htm")-Len("http://"))

Response.write(urlstr)

<%
mystr="http://www.aaa.com/bbb/ccc/index.htm"
mystr=split(mystr,"/index.htm")
for i=0 to ubound(mystr)
response.write mystr(i)
next

%>

link="http://www.aaa.com/bbb/ccc/index.htm"
