jaswope / rack-reverse-proxy Goto Github PK

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?

Guys,

this is small cool project yet current maintainer clearly has no time/will to maintain it.

Is there someone better suited for the job who would like to take over?

If not, I'd be happy to help as it looks like I'll be using this library more and more in upcoming months.

Hello,
my old API website requires http basic auth (or oauth) in order for a user to gain access to the page.

In my new Rails app I mounted rack-reverse-proxy but I'd like to know if it's possible to also forward the custom user/password combo the user is asking my app.

Is that possible?

Hi, I'm using this project to redirect requests in an existing heroku app that has been moved to a more powerful cluster.

Redirects occur fine but I need one of the headers that the devices are sending to heroku, to be sent to the cluster where the proxy is pointing at.

(I'm not a ruby dev so please bear with me)

config.ru (if it helps)

require 'rack/reverse_proxy'

use Rack::ReverseProxy do
  reverse_proxy_options :preserve_host => true
  reverse_proxy '/', 'http://example.com'
end

app = proc do |env|
  [ 200, {'Content-Type' => 'application/json'}, "b" ]
end

run app

This seems to only preserve the request body on PUT and POST request methods. AFAIK, the standards do not explicitly prohibit a request body on a DELETE request, so the reverse proxy shouldn't either.

I have setup a rake task to refresh the sitemap of an application, and it's hosted in S3, because we're using heroku. Can I use this to reverse proxy in this case? I tried but I get an error

<Error>
  <Code>InvalidArgument</Code>
  <Message>Unsupported Authorization Type</Message>
  <ArgumentName>Authorization</ArgumentName>

Here's my config in config/production.rb:

Heroku logs output:

Went off this blog post:

I realize I didn't use the RegEx, but I got a similar result when I did.

thank you!

Right now, a PATCH request gives you "method not supported: PATCH"

:preserve_host, when set to true, causes the Host header to be overridden, not to be preserved, unlike Apache's ProxyPreserveHost, which has the semantics you would expect.

In other words, given Rack app A reverse-proxying to B, with :preserve_host => false, it will send "Host: A", and with :preserve_host => true, it will send "Host: B".

It should be the other way around, i.e. false sends B and true sends A, so that the option means what it says, and to be consistent with Apache.

The default should probably be to not preserve the host, like Apache. (I'm not sure about the current default...)

I had to create a reverse proxy for encoded_uri in this URL:

/proxy?url=encoded_uri

The configuration of the proxy:

  reverse_proxy /^\/proxy\?url=(.*)$/, "$1", :preserve_host => false

The problem is that the implementation of get_uri doesnt take into account the URL encoding of the parameter and it returns:

https%3A%2F%2Fgithub.com%2Fjaswope%2Frack-reverse-proxy%2Fissues%2Fnew

which causes an internal server error.

My fix:

class Rack::ReverseProxyMatcher

  alias_method :get_uri_without_decode, :get_uri

  def get_uri(path,env)
    puts 'this is a monkeypatched method for :get_uri'
    url = get_uri_without_decode(path,env)
    if url.path.start_with?('http%')
      url = URI.decode url.path
      url = URI(url)
    end
    url
  end
end

Just wondering if this gem could be used as a development/test load balancer that a dev could run locally. I was looking for a simple way to start two http apps and just have this toggle between the two when http requests come in.

Thank you for this great gem.
I would like to show the contents from a URL with subdirectory at the http://example.com/ (Rails app).
I configured config/application.rb as following, but this does not work.

module MyRailsApp
  class Application < Rails::Application
    config.middleware.use Rack::ReverseProxy do
      reverse_proxy_options preserve_host: true
      reverse_proxy /^\/$/, 'http://example-2.com/example-page'
    end
  end
end

But this configuration only shows "http://example-2.com/" not "http://example-2.com/example-page”.
Is this usage supported?

Hi,

I have reverse proxy setup for a subfolder to a wordpress blog, which is hosted on an ec2 server. Ultimate goal "https://www.example.com/blog/" The problem is the parent site is in https, so for transparency I've added openssl to the lamp stack(ec2). The problem is that the wordpress blog is not showing any assets/css.

routes:
#wordpress
match "/blog" => redirect("/blog/")

config.ru

use Rack::ReverseProxy do
reverse_proxy /^/blog(/.*)$/, 'http://xx.xx.xx.x$1', opts={:preserve_host => true}
end

xx.xx.xx.x = ip to the ec2 box with wordpress installed.
