Fix redirects for some AVR models #19

Open milaq opened 5 years ago

milaq commented 5 years ago

Some AVR models don't follow 302 redirects for some reason.

First try on finding out what works and what doesn't: https://github.com/milaq/YCast/tree/redirect_shenanigans

https://github.com/milaq/YCast/commit/053bdfa5fabe80d10bdb690488c6dcd10fe306ac is working.

It seems like some Yamaha AVRs have a built-in whitelist and are discarding any non-matching redirects.

I reckon that the receiver just checks the Baseurl of the request (i.e. http://radioyamaha.vtuner.com).

milaq commented 5 years ago

Assumption confirmed.

Some Yamaha AVRs only accept redirects if the headers include http://radioyamaha.vtuner.com.

milaq commented 5 years ago

Maybe the whitelist checks something like this:

If HOST or REFERER or ORIGIN begins with http://radioyamaha.vtuner.com then pass

We should implement vendor specific url overrides to mitigate the issue some users are having with some AVRs which put the wrong information into the host header.
