no-cookies, no-cache-validate channels for /ipfs/ paths?

[the8472]

As noted in 4296e7d setting nsIRequest.LOAD_ANONYMOUS and VALIDATE_NEVER on requests to gateways might make sense.

Cookies set while explicitly browsing http://gateway.tld/foo/bar pages shouldn't have anything to do with the gateway services themselves, and there's no meaningful way to expose them to content anyway.
And /ipfs/ paths should be forever stable, so we can be pretty sure that they don't need any cache validation, no matter what the server says.

• I agree on nsIRequest.VALIDATE_NEVER for /ipfs/, it would not hurt to set it.
• nsIRequest.LOAD_ANONYMOUS: I am bit worried that blocking cookies may cause some unknown consequences, eg. break some static apps that use them for simple things like storing theme/font size preference, game saves etc.
  Question: does it also block localStorage?

[Kubuxu]

localStorage is disabled where there is no authority part in URI.

After giving it some thought I think would be ok to enable nsIRequest.LOAD_ANONYMOUS when fs: is set as a target protocol handler (#70).
Even if we set fs: as a default, there will be an option to disable it and fallback to http-based URLs, in which cookies and localStorage work in old school way.

This should be good enough for now, at least until we have #71 sorted out.
