如何手动清除LinkedIn共享程序的缓存
通过LinkedIn API使用共享功能时，网站的每个页面都将传送一张相同的图片 http://hrm.mysitedemo.co.uk
图片已缓存在服务器上.
服务器上此图片的地址为:链接
您能告诉我们如何手动清除缓存吗?
At using share function via LinkedIn API, one and the same picture is transfered for each page of the website http://hrm.mysitedemo.co.uk
The picture is cached on the server.
The address of this picture on server is: link
Address that leads to share dialog window is : link
Could you please tell how to to clear the cache manually?
通过LinkedIn共享的内容由LinkedIn的服务器缓存了大约7天.除了等待缓存过期之外，目前没有其他方法可以手动清除缓存.
Content shared via LinkedIn is cached by LinkedIn's servers for a period of ~7 days. There is presently no way to manually clear the cache other than waiting for it to expire.
一种可能的短期解决方法是，在网址末尾添加一个垃圾"参数，例如 http://example.com/mypage.html?donothing=1
One possible short-term work-around is to modify your URL with a "garbage" parameter at the end of it, e.g. http://example.com/mypage.html?donothing=1
如果您的网站不会根据您添加的参数更改显示的内容，LinkedIn将看到它是一个不同的URL，并且您不会获得旧的缓存版本.
Provided your site does not change the content displayed based on the parameter you append, LinkedIn will see that as a different URL and you won't get the old cached version.
