Apache Reverse Proxy – Proxypass Changing URL

apache-2.4PROXYreverse-proxyurl-routing

I am trying to connect my jupyter notebok server (:8888 port) via reverse proxy server

I have such rules:

ProxyPass "/serv8888"  "http://localhost:8888"
ProxyPassReverse "/serv8888"  "http://localhost:8888"

ProxyPass "/"  "http://localhost:80"
ProxyPassReverse "/"  "http://localhost:80"

but when I connect to http://localhost/serv8888 it redirects internally to http://localhost:80/tree and basically I get http://localhost/tree and it does not work because I need to get

http://localhost/serv8888/tree what also means internally http://localhost:8888/tree

How to make it working? Please help me, I spent two days and almost gave up

The problem is that your "jupyter notebook server"'s internal redirect is attempting to undo what the proxy-pass is trying to do. ProxyPass does not re-write content returned by the proxy's site. It simply proxies communication to another web server. If that other web server says go to "/some/url"... proxy pass will not change that.

You need to modify the jupyter's config and specify the NotebookApp.base_url to "/serv8888/"... and then proxypass will work for you.

I have done that by the following code. You can try it...

    ProxyPreserveHost On
    <Proxy *>
            AddDefaultCharset off
            Order deny,allow
            Deny from all
          Allow from all
    </Proxy>

            ProxyPass /google http://www.google.com/
            ProxyHTMLURLMap http://www.google.com /google

    <Location /google>
            ProxyPassReverse /
            ProxyHTMLInterp On
            ProxyHTMLURLMap  /      /google
            RequestHeader    unset  Accept-Encoding
    </Location>

NGINX Reverse Proxy – URL Rewrite

Any redirect to localhost doesn't make sense from a remote system (e.g. client's Web browser). So the rewrite flags permanent (301) or redirect (302) are not usable in your case.

Please try following setup using a transparent rewrite rule:

location  /foo {
  rewrite /foo/(.*) /$1  break;
  proxy_pass         http://localhost:3200;
  proxy_redirect     off;
  proxy_set_header   Host $host;
}

Use curl -i to test your rewrites. A very subtle change to the rule can cause nginx to perform a redirect.
