网页开发如何使用HTTPS

让一个ASP页面以https开始，请在该ASP页面顶部添加如下代码：

<%
Response.Buffer = True
If (Request.ServerVariables("HTTPS") = "off") Then
Dim xredir__, xqstr__

xredir__ = "https://" & Request.ServerVariables("SERVER_NAME") & _
Request.ServerVariables("SCRIPT_NAME")
xqstr__ = Request.ServerVariables("QUERY_STRING")

if xqstr__ <> "" Then xredir__ = xredir__ & "?" & xqstr__

Response.redirect xredir__
End if
%>

相反的，强迫以Http开始
请添加如下代码

<%
Response.Buffer = True
If (Request.ServerVariables("HTTPS") = "on") Then
Dim xredir__, xqstr__

xredir__ = "http://" & Request.ServerVariables("SERVER_NAME") & _
Request.ServerVariables("SCRIPT_NAME")
xqstr__ = Request.ServerVariables("QUERY_STRING")

if xqstr__ <> "" Then xredir__ = xredir__ & "?" & xqstr__

Response.redirect xredir__
End if
%>
