Passing cookies to a capture can be confusing

[Rafiot]

Current situation

When passing a list of cookies to a capture, they are sometimes ignored, and it can happen for the following reasons:

• the cookies are for foo.domain.com and when the URL passed to the capture is domain.com and it redirects to foo.domain.com. In that case, the cookies are never added in splash cookie jar and will not be sent to the redirect
• The cookies have the secure key set, and the capture is done on http://domain.com, with a redirect to https://domain.com: they won't be sent to the initial URL and never added in splash cookie jar.

TODO

1. Document that on lookyloo.eu
2. Figure out a way to properly initialize the cookie jar on splash
