java web开始多次请求jar文件

Question

我正在使用icedtea javaws (版本: icedtea-web 1.6.2 (1.6.2-3ubuntu1))来分发我的java应用程序。

我的jnlp文件如下所示：

<jnlp spec="1.0+" codebase="/">  
    <information>  
            <title>My Application</title>  
        <vendor>Software Studio</vendor>      
        <offline-allowed/>  
    </information>
    <resources>
        <!-- Application Resources -->
        <jar href="MyApplication-1.0.jar"></jar>
    </resources>
    <application-desc main-class="com.myapp.application.Application">
        <!-- Application Arguments -->
    </application-desc>
    <security>
        <all-permissions/>
    </security>    
</jnlp>

应用程序jnlp文件和资源MyApplication-1.0.jar文件托管在apache web服务器中。我在访问日志中注意到，一些客户端在短时间内多次请求jar文件。下面是我的apache access_log文件中显示此问题的内容的一个片段：

客户端通过执行javaws命令来运行应用程序，将jnlp url作为参数传递。

javaws -headless https://myapplication.com/MyApplication.jnlp

是什么导致了这种行为？

IcedTea-Web1.6.x是一个相当旧的版本。您可以尝试更新到1.8.x或尝试使用openwebstart.com吗？它基于IcedTea-Web2.0.x，并提供了一些附加功能
