1476978 - Provide APIs for Necko to perform redirection of top-level loads to a new process

Status: RESOLVED DUPLICATE of bug 1476996

(Core :: DOM: Navigation, enhancement)

Description

[Honza Bambas (:mayhemer)]

According the agreed design we need two functions to be called by channels on the parent process:

1. (in case the load has not been redirected) determination if consummation of the response should happen in a new process

2. redirection of the response to a new process with passing down the following data:
  - originalURL (first URL of the redirect chain)
  - targetURL (the URL to create the channel with, the one we actually navigate to)
  - resultPrincipalURL (null, or a URL to set on the channel's load info as the principal URL)
  - probably load flags of the channel
  - redirect ID (uint64_t that must be set on the loading channel before opening via nsIChildInterface)

The second function will start the whole process of finding or creating the new process and passing the necessary arguments to docshell to setup the channel and then open it.

Note that HttpChannelChild::SetupRedirect may be a good example of what all we may need to carry to the new channel...  not a small amount.

[Nika Layzell [:nika] (ni? for response)]

I'm not sure why I am marked as the assignee on this bug - I was imagining that necko would implement a no-op version of the interface which we could replace once it had been implemented and tested :-).

We handle all this in bug 1476996.
