问题描述
其中添加了以下代码.在AddHeader中，对所有固定的"Pragma"是固定的
var lastModified = DateTime.UtcNow;
var expires = lastModified-TimeSpan.FromDays(365);
Response.Cache.SetExpires(expires);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();
Response.CacheControl =无缓存";
Response.AddHeader("Pragma"，"no-cache");
where the following code is added .in AddHeader what is "Pragma" is it fixed for all
var lastModified = DateTime.UtcNow;
var expires = lastModified - TimeSpan.FromDays(365);
Response.Cache.SetExpires(expires);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetNoStore();
Response.CacheControl = "no-cache";
Response.AddHeader("Pragma", "no-cache");
推荐答案
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetCacheability(HttpCacheability.NoCache);
我相信，仅靠它自己就能解决问题.无论哪种方式，无论将其放在哪里，都可以将所有这些代码放在页面中或您使用的基类中.
by itself will fix the problem, I believe. Either way, putting all this code somewhere in your page, or in a base class that you use, will work, no matter where you put it.
<html>
<head>
<meta HTTP-EQUIV="REFRESH" content="5">
<title>New Title </TITLE>
</head>
<body>
Blah !! Blah !! Blah !! Blah !! Blah !!
</body>
<head>
<meta HTTP-EQUIV="PRAGMA" content="NO-CACHE">
</head>
</html>
