ASP怎么實現(xiàn)301重定向

    使用301重定向可以把不帶www的域名轉向帶www的域名，這樣可以把權重全部指向帶有www的域名，對網(wǎng)站優(yōu)化很有幫助。
    <% Dim Server_Name,Path_infostr,Query_Stringstr Path_infostr=lcase(request.ServerVariables("PATH_INFO")) Server_Name=lcase(request.ServerVariables("Server_Name")) Query_Stringstr=request.ServerVariables("Query_String") If Query_Stringstr<>"" Then Query_Stringstr="?"&Query_Stringstr IF instr(Server_Name," Then Response.Status = "301 Moved Permanently" if instr(Path_infostr,"index")>0 or instr(Path_infostr,"default")>0 Then Response.AddHeader "Location","
    Else Response.AddHeader "Location","End if Response.End End if %>
