问题描述

I'm using icedtea javaws (version: icedtea-web 1.6.2 (1.6.2-3ubuntu1)) to distribute my java application.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。

My jnlp file looks like this: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>

The application jnlp file and the resource MyApplication-1.0.jar file are hosted in an apache web server.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。 I've noticed in the access logs that some clients are requesting the jar file multiple times in a short period of time.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。 Below is a snippet of the content of my apache access_log file showing this issue:下面是我的 apache access_log 文件的内容片段，显示了这个问题：

Clients are running application by executing the javaws command passing the jnlp url as a parameter.客户端通过执行将 jnlp url 作为参数传递的 javaws 命令来运行应用程序。

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