Using ASP to implement HTTP://XX@XX.XX virtual domain name

To give you my ideas, I hope to some interested friends a little help:

First of all must have their own top-level domain name:-), but also sacrifice their own home index.asp name (for example: "The homepage renamed to Index1.asp, but in the program can be judged without the @ parameters of the domain name and then jump to the home page)."

First, the default first page in the root directory of the domain name index.asp as the get @ before parameter jumps
Index.asp



go.asp processing domain names and implementing jumps

'获取URL参数
url=request.QueryString("url")
'判断是否是以虚拟@域名形式传递过来
ifinstr(url,"@")=0then
'如果没有则直接跳转到自己的首页index1.asp

else
'处理url参数,取得中的username
url=right(url,(len(url)-len("http://")))
url=left(url,(instr(url,"@")-1))
user=url
'从数据库中取出于username对应的转向目标url地址
setrs=conn.execute("selectsiteurlfromurlwhereuser='"&user&"'")
ifrs.boforrs.eofthen
'如果没有记录则显示:该域名不存在
response.Write("<ahref='http://skyworm.com'><fontsize=2><center>该域名不存在</center></font></a>")
else
'对域名访问率简单记数
conn.execute("updateurlsetcount=count+1whereuser='"&user&"'")
'跳转到虚拟域名对应的目标url地址,程序结束!
response.Redirect(rs(0))
endif
rs.close
setrs=nothing

conn.close
setconn=nothing
