兼容:

<!--如果检测到是http页面，则自动跳转到对应的https页面--> <scripttype="text/javascript"> if(document.location.protocol!="https:"){ location.href=location.href.replace(/^http:/,"https:"); } </script>

ASP:

<% IfRequest.ServerVariables("SERVER_PORT")=80Then DimstrSecureURL strSecureURL="https://" strSecureURL=strSecureURL&Request.ServerVariables("SERVER_NAME") strSecureURL=strSecureURL&Request.ServerVariables("URL") Response.RedirectstrSecureURL EndIf %>

PHP:

if(!isset($_SERVER['HTTPS'])||!$_SERVER['HTTPS']){ $url='https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; header('Location:'.$url);exit; }
