解决方案

您不能从所有站点中删除用户的所有cookie，只能删除站点中的cookie.此外，cookie和缓存是非常不同的东西.要停止缓存网站，请使用C#，它是:

 Response.ExpiresAbsolute = DateTime.Now.Subtract(新 TimeSpan( 1  ， 0 ， 0 ， 0 )) ;
Response.Expires =  0 ;
Response.CacheControl = " ; 

在页面的On_Load方法中.将其转换为VB并不难.关于cookie，该网站似乎在底部有一个很好的例子和良好的链接，包括删除cookie:
http://www.java2s.com/Code/ASP/Session-Cookie/WriteCookieandreadCookieVBnet.htm [ ^ ]

您可能想要使用C#，但是将其转换为C#看起来非常简单.

下一次注意，请尝试搜索自己. Google和CP通常会很容易为此类问题提供答案，我知道我们之前也有类似的问题，因此您可能会发现.

无论如何，希望这会有所帮助，

如果您试图从用户运行的Windows Forms应用程序中进行操作，则必须为要支持的每种浏览器编写一个单独的模块.没有两个浏览器以相同的方式清除其缓存/cookie，并且每个浏览器都没有公开一个API来执行此操作.

您可以在IE购买Google搜索中搜索"VB.NET清除IE cookie缓存".

解决方案

You cannot delete all the cookies of a user, from all sites, only cookies from your site. Furthermore, cookies and cache are very different things. To stop caching of your website, in C#, it would be:

Response.ExpiresAbsolute = DateTime.Now.Subtract(new TimeSpan(1, 0, 0, 0));
Response.Expires = 0;
Response.CacheControl = "no-cache";

In the On_Load method of your page. It shouldn''t be too hard to convert that to VB. With regards to cookies, this site seems to have a good example and good links at the bottom, including deleting a cookie:
http://www.java2s.com/Code/ASP/Session-Cookie/WriteCookieandreadCookieVBnet.htm[^]

One you may want is in C# but it looks very simple to convert to C#.

Note for next time, try searching for yourself. Google and CP will normally give the answers very easily for this sort of question, I know we''ve had one similar to this before so you could have found that.

Anyway, hope this helps,

Ed :)

If you''re trying to do with from a Windows Forms app the user runs, you''ll have to write a seperate module for every browser you want to support. No two browsers clear their caches/cookies the same way and there is no single API that every browser exposes to do it.

You can look at IE buy Googling for "VB.NET clear IE cookies cache".
