NSIS下载超时

Question

我已经建立了一个NSIS，它已经可以正常工作几个月了，突然，JRE的下载失败出现了问题，我已经测试了下载链接是否正常，请提出以下可能的解决方案，如果有人可以帮助部分代码，则列出如下：

!define JRE_URL "javadl.sun.com/webapps/download/AutoDL?BundleId=69476"
Function GetJRE
    MessageBox MB_OK "${PRODUCT_NAME} uses Java ${JRE_VERSION}, it will now \
                     be downloaded and installed"

    StrCpy $2 "$TEMP\Java Runtime Environment.exe"
    nsisdl::download /TIMEOUT=30000 ${JRE_URL} $2
    Pop $R0 ;Get the return value
            StrCmp $R0 "success" +3
            MessageBox MB_OK "Download failed: $R0"
            Quit
    ExecWait $2
    Delete $2
FunctionEnd


Function DetectJRE

nsisDl使用自定义HTTP库。使用INetC代替，它使用与Internet Explorer相同的HTTP库。
