Create an HTTP global state object

[jdm]

We pass around stuff like the cookie storage, the HSTS list, the HTTP authentication cache, etc. in http_loader.rs. This also means that the unit tests have a lot of repeated initialization code that creates these objects even when they're not used. I propose we wrap them up in a struct and give it a argument-less constructor to make reading the code easier and require fewer changes when adding additional global HTTP state.

Code: components/net/http_loader.rs, components/net/resource_thread.rs, tests/unit/net/http_loader.rs

You would still be passing around that one object, right?

[jdm]

Yes.

Should this state object include things like LoadData, or only things that can be initialized without any parameters?

ex. LoadData is setup in a test like:

let mut load_data = LoadData::new(LoadContext::Browsing, url.clone(), None);
load_data.data = None;
load_data.method = Method::Get;

[jdm]

LoadData is a per-request object, so it would not be included.

@jdm ok makes sense, currently I have:

hsts_list
cookie_jar
auth_cache

included in the http global state object, should anything else be included/excluded?
