Description Ben Nham 2023-03-01 11:20:19 PST

There are a lot of callsites in NetworkProcess that manually create a PreconnectTask with differing NetworkLoadParameters:

* NetworkProcess::preconnectTo - used to preconnect to main resources
* NetworkConnectionToWebProcess::preconnectTo - used to handle preconnects created by `<link rel="preconnect" ...>`
* SpeculativeLoadManager::preconnectForSubresource - used to preconnect to subresource domains speculatively

And then in 253120 I've added another callsite `EarlyHintsResourceLoader::startPreconnectTask`.

It seems like we should be able to unify these callsites into something a bit saner.
