[BUG] Optimize local cache of *.wasm files

Bug Description and Steps to Reproduce

3.8 增加了 openIM.wasm 本地缓存，的确解决加载缓慢问题。但是是通过 etag 与 last-modified 来判断是否需要更新，但这种方式一但重写发布新 Docker Image 时文件的修改时间会发生改变，但实际上我们 wasm 几乎很少会变化，这种变化是打包工具的原因。

建议在缓存逻辑上可以增加一个以 URL Path 作为 Key 就好的选项。

I don't quite understand what this does, and the URL doesn't seem to change.
