The proxy is redirecting to the root domain of the forwarded address.

[jonathan-mui]

I have a domain "https://www.example.com".
I've setup my config.ru to do the simple forward shown in the wiki

reverse_proxy /^\/blog(\/*.*)$/, 'http://myblog.tumblr.com$1'

However, when I try to visit "https://www.example.com/blog", it redirects to "https://www.tumblr.com". Is this expected?

Check the Location header in the redirect you are receiving. rack-reverse-proxy does not rewrite those, and if a full URL is in the Location header (and not a path), you'll get this issue.

I'm facing this issue. My Location header is a full URL.
How can I make my app response only the path for this redirect?

Thanks for help in advance

For anyone having same issue, as I do:
use reverse_proxy_options replace_response_host: true, along with other options.
