系统环境：Linux RedHat AS5.0＋Apache 2.2（端口7001）＋WebLogic9.2（端口8002、8003、8004）
WebLogic 为集群布署，由Apache做代理服务器。结果直接访问WebLogic服务器的htc文件能够正常访问（如：在IE栏输入 :8002/test/test.htc，可以获取到文件，提示下载），但如果通过Apache访问则显示空白，什么也没有（如：在IE栏输入:7001/test/test.htc，显示空白，同时鼠标右键无用）。

RESOLUTION
You can resolve the problem on the Apache Web server side if you add the correct MIME type for the HTC behavior with the following command:
AddType text/x-component .htc
If the command AddType is not found or is not available, follow these steps to add the MIME type text/x-component for the .htc file manually to the Apache Web server.
1. Locate the directory /Etc/apache/.
2. Open the file Mime.types.
3. Add the following line to the file: text/x-component htc
4. Save and close the file.
5. Restart the Apache Web server. The Mime.types file is reloaded after you type: /usr/apache/bin/apachectl restart STATUS

HTC (HTML Component) HTML组件——从5.5版本开始，Internet Explorer（IE）开始支持Web 行为的概念。这些行为是由后缀名为.htc的脚本文件描述的，它们定义了一套方法和属性，程序员几乎可以把这些方法和属性应用到HTML页面上的任何元素上去。采用HTC带来的好处是巨大的。但是由于 HTC 是 Microsoft 提出的技术。 【ＬＩＮＵＸ公社 】

注：Linux AS4默认的apache，配置了MIME类型也无法正常使用.htc组件，建议使用源代码编译安装。
另外：weblogic、WebSphere 中无法正常使用htc组件
*** 解决方法则是在 WebApp 的 web.xml 中加入以下几行
<mime-mapping>
<extension>htc</extension>
<mime-type>text/x-component</mime-type>
</mime-mapping>
