为什么很长的url在chrome下没问题，在ie下就变成下载了呢。

代码是这样的



<iframe src="" id="login_ifr" style="display: none;" width="800px" height="800px"></iframe>

<script>

window.onload = function(){enter();}

function enter()

{

    document.getElementById('login_ifr').src="/index.php/Auth/getLink";

}

/index.php/Auth/getLink的页面会输出



<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><script>window.location='http://www.abc.cn/basic_home.php/Login_edu/login_3rd/hash/fd6427d88b8aca436ea5614059e5a7ba/back2url/aHR0cDovL2Vjc2hvcC5maHh4dy5jbi9lY3Nob3AvZ29vZHMucGhwP2lkPTE0Mg=='</script>

chrome内核的浏览器都没问题。ie内核的浏览器在执行window.location='http://www.abc.cn/basic_home.php/Login_edu/login_3rd/hash/fd6427d88b8aca436ea5614059e5a7ba/back2url/aHR0cDovL2Vjc2hvcC5maHh4dy5jbi9lY3Nob3AvZ29vZHMucGhwP2lkPTE0Mg=='的时候会提示下载文件。而不解析HTML。

虽然这个是IE浏览器才出现的问题，但是没有IE板块。但是我后端用的php语言，所以投递到php板块了。
