   Also, Python's `urljoin` function has documented a warning about similar behavior:
   <https://docs.python.org/3.13/library/urllib.parse.html#urllib.parse.urljoin>
 
-  ## PoC
-
-  Follow these steps to reproduce the issue:
-
-  1. Set up two simple HTTP servers.
-
-     ```bash
-     mkdir /tmp/server1 /tmp/server2
-     echo "this is server1" > /tmp/server1/index.html
-     echo "this is server2" > /tmp/server2/index.html
-     python -m http.server -d /tmp/server1 10001 &
-     python -m http.server -d /tmp/server2 10002 &
-     ```
-
-  2. Create a script (for example, `main.rb`):
-
-     ```rb
-     require 'httparty'
-
-     class Client
-       include HTTParty
-       base_uri 'http://localhost:10001'
-     end
-
-     data = Client.get('http://localhost:10002').body
-     puts data
-     ```
-
-  3. Run the script:
-
-     ```bash
-     $ ruby main.rb
-     this is server2
-     ```
-
-  Although `base_uri` is set to `http://localhost:10001/`, httparty sends the request to `http://localhost:10002/`.
-
-
   ## Impact
 
   - Leakage of credentials: If an absolute URL is provided, any API keys or credentials configured in httparty may be exposed to unintended third-party hosts.
