`provideClientHydration()` accepts new `HydrationFeature` : `HttpTransferCacheOptions`.
`withHttpTransferCacheOptions` accepts an option object:
* `includeHeaders` : list of headers entries to keep in the cache with the request
* `filter` a callback to determine if a request should be cached
* `includePostRequests`: to include POST requests in the allowed methods
Implements some of the features requested in #50117
PR Close#52029
This commit adds support by default for HTTP caching when using `provideClientHydration`. Users can opt-out of this behaviour by using the `withoutHttpTransferCache` feature.
```ts
import {
bootstrapApplication,
provideClientHydration,
withNoHttpTransferCache,
} from '@angular/platform-browser';
// ...
bootstrapApplication(RootCmp, {
providers: [provideClientHydration(withNoHttpTransferCache())]
});
```
PR Close#49699
This commit adds a new option for `provideHttpClient` called
`withHttpTransferCache()`. When this option is passed, requests done on the server are cached and reused during the bootstrapping of the application in the browser thus avoiding duplicate requests and reducing load time.
This is the same as `TransferHttpCacheModule` in https://github.com/angular/universal/blob/main/modules/common/src/transfer_http.ts
