https://mysite.dev returns error

[BeerInHand]

Started prax with "prax start -f" - everything runs fine until I navigate into a secure section of the site that uses https and this error is returned:

This is on a fresh install of Ubuntu 14.04 LTS,. Is there some addition setup required to use ssl?

[ysbaddaden]

There shouldn't be more configuration required, as long as Prax is listening on :20558

You hit the dreadful bug that makes the host non determinable (prax can't proxy without a host to like the app to). Could you inspect the request sent from the browser? That would help debug.

So I was wrong earlier when I said prax would serve no https requests - it does handle some https pages just fine. What I think is the issue is that the pages that error have a force_ssl = true. When it attempts to redirect to https is goes into an infinite redirect loop - as if it can't tell that the https protocol was already in use.

Here's the request headers:

... repeated until browser gives up with "The page isn't redirecting properly" .

SSL never reaches the application itself. Prax will handle the HTTPS part and only tells the application about it with the X-Forwarded-Proto: https HTTP header. Maybe your application expects something else?

Prax must intercept/handle the HTTPS otherwise it wouldn't be able to know which application or port to proxy the request to.
