问题描述
我正在运行一个适用于Chrome和Firefox的简单HTML5应用。它使用Web worker，如下所示：
I am running a simple HTML5 app that works in Chrome and Firefox. It uses a web worker, as in:
var worker = new Worker("the/worker/URL/Code.js");
我在IE中试验了一个多小时，我终于发现网络工作者的代码永远不会重新加载。当我得到它的版本时，抛出一个错误，调试器显示了一个完全过时的工作代码文件版本，即使所有其他文件都已正确重新加载。
I have experimented for over an hour in IE, and I finally found that the web worker's code is never reloaded. When I get the version that it has, to throw an error, the debugger shows me a completely outdated version of the worker code file, even though, all other files have been reloaded properly.
我刷新缓存，使用到处找到的标准建议：安全 - >删除浏览历史 - >选择项目 - >确定 - >等待 - > Ctrl + F5重新加载 - > BAM，调试器仍显示100％与几个小时前相同的文件（请记住，重新加载在Chrome和FF中按预期工作）。
I flushed the cache, using the standard advice found everywhere: Safety -> Delete Browsing History -> Select items -> Ok -> Wait -> Ctrl+F5 to reload -> BAM, thee debugger still shows 100% the same file as several hours ago (remember that reloading works as expected in Chrome and FF).
当我查看网络分析器时，我看到：
When I look at the Network profiler, I see:
URL Protocol Method Result Type Received Taken Initiator Wait Start Request Response Cache read Gap
/js/core/WorkerScriptCode.js (Pending...) GET (Pending...) (Pending...) 0 B (Pending...) webworker 1311 0 0 0 0 31
我不知道为什么会说待定;我可以看到工作者已经运行：我可以看到工作人员的工作已经完成（例如 importScripts 调用显示，还有上面提到的堆栈跟踪）。但它只是运行一个完全过时的版本，即使我将整个缓存刷新了几十次。
I don't know why it says "Pending"; I can see that the worker already runs: I can see the work of the worker being done (e.g. the importScripts calls show up, and there are also above mentioned stacktraces). But it simply runs a completely outdated version, even though I flushed the entire cache tens of times.
这是一个超级错误，还是我是愚蠢的？
Is this an uber-bug, or am I being stupid?
推荐答案
Chrome中存在同样的问题。为了解决这个问题，您可以使用缓存破解程序：
The same problem exists in Chrome. In order to get around it you can use a cache buster:
主要代码：
var buster = randomNumberOrBuildNumber;
var worker = new Worker( "the/worker/URL/Code.js?buster=" + buster );
工人：
importScripts( 'script/to/import.js' + self.location.search );
这将适用？buster = 12345 （或者你的 randomNumberOrBuildNumber 被设置为）加载工人和任何 importScripts（）调用工人制作。
This will apply ?buster=12345 (or whatever your randomNumberOrBuildNumber is set to) to both the loading of the worker and any importScripts() calls the worker makes.
