Repeated loading of resource requests for web extensions

[yiliang114]

Reproduction steps：

1. Open vscode.dev
2. Open devtools and search package
3. When refreshing the page, you will find that there are some duplicate resource loads such as package.json or package.nls.xxx.json

When you say duplicates are you saying they are duplicates of the same package.json? Keep in mind we need to load once the the package.json AND the package.LOCALE.json of each extension.

Yeah, it's the same file. For example, I search for keywords vscode-pull-request-github （provided that I have this extension installed）， Many duplicate locale files with the same name will appear in the debug panel.

We rely on browser cache here as these requests set proper cache headers and browser serves them from cache. May be you have disabled the cache.

In fact, I did not disable the cache, and the same resource will indeed be requested repeatedly. However, it is also true that the browser's strong cache or negotiation cache will hit, so the actual impact on the loading speed may be very small.

What will have an impact is actually that in the network panel, many repeated requests are very unfavorable for resource search and problem investigation.

That's true, but that does not mean an application client should cache request responses. It is error prone. For diagnosing you can also use filtering in the network tab.
