解决nat123之后速度慢的问题，使用javascript定时跳入带端口号的网址

<script>
function optimize(aurl){ 
//alert(window.location.port);    
if(window.location.port==''){         
setTimeout(function(){             
//要执行的代码               
//window.location.port=aport;             
//window.location.hostname=aurl; 
 
window.location=aurl+window.location.pathname+window.location.search+window.location.hash;                         
},3001);   
} 
}
optimize("http://job.0391rcw.com:8081");
</script>

将以下代码放在jquery的最前端，则不会影响seo，还能立即跳转

function optimize(aurl){ 



if(window.location.port==''){ 
        

setTimeout(function(){             

 window.location=aurl+window.location.pathname+window.location.search+window.location.hash;                         

},10);   

} 

}

optimize("http://job.0391rcw.com:8081");
