Sleep on production, to prevent endless redirection

This line seems odd:

+    $server = $server = rtrim(variable_get('stage_file_proxy_origin'), '/');

You want to be really sure the $server variable is set? ;)

As axel.rutz says, it works for me as well. Thanks for this patch, Axel!

Thanks for the patch and review! Now applied.

I made a slight tweak to the comment to make it more clear where/why https is being ignored.

Does this apply to 8.x?

@greggles,

Yes, I've successfully applied to 8.x.

@asrob successfully applied what to 8.x? the patch as it stands certainly doesn't apply. Did you mean to upload something?

@greggles,

oops, sorry. You're right, it does not work in 8.x. I did not remember correctly because I've tested another patches for 8.x.
