Is there any way to make this solution work on IE9???

推荐答案

请参阅我对问题的评论.您怎么知道问题完全与Web浏览器有关?您尝试过其他浏览器吗?

您应该始终牢记，一个网站可以轻松地保护图像，使其免受另一域中服务的另一端的使用.这是因为HTTP服务器接收到包含发件人IP的HTTP请求，因此该服务器始终可以应用某些限制.甚至可以在托管级别完成此操作，这会将此选项转换为服务器配置(通常是针对虚拟端).我当前的Web托管提供商有这样的选择.这称为热链接保护.要了解一个想法，请参见:

Please see my comments to the question. How do you know that your problem is related to a Web browser at all? Did you try with other browsers?

You should always keep in mind that a Web site can easily protect images from being used by another side serving on a different domain. This is because an HTTP server receives an HTTP request which contains a sender IP, so the server can always apply certain limitations. This can even be done at the level of hosting, which translates this option into the server configuration, typically for a virtual side. I have such option with my current Web hosting provider. This is called hotlink protection. To get an idea, please see:
