⁠AsyncProxy - Python Programming Task

Your task is to build an asynchronous HTTP proxy (see definition in RFC2616⁠) complying to the requirements specified below.

⁠Requirements

1. Range requests must be supported as defined in RFC2616⁠, but also via range query parameter.

2. HTTP 416 error must be returned in case where both header and query parameter are specified, but with a different value.

3. Program must start with a single command docker-compose up.

4. Proxy must be reachable at http://<docker-host>:8080 .

5. Usage statistics must be available at http://<docker-host>:8080/stats

• total bytes transferred
• uptime

1. Code must run with Python 3.5+.

2. Code must be delivered as a link to public GitHub repository.

⁠Design

1. I built a simple AsyncProxy server based on aiohttp⁠. The reasons are:
   • aiohttp is based on asyncio — Asynchronous I/O, event loop, coroutines and tasks module og python 3.4+⁠
   • aiohttp supports both Client and HTTP Server.
   • aiohttp supports both Server WebSockets and Client WebSockets out-of-the-box.
   • aiohttp Web-server has Middlewares, Signals and pluggable routing.
2. The default proxy target server is set to http://youtube.com⁠
   • Browsing http://localhost:8080⁠ will response with the content of http://youtube.com⁠
   • Browsing http://localhost:8080/stats⁠ will give the current stats of the AsyncProxy server.
   • Browsing http://localhost:8080/?target_url=http://python.org⁠ will change proxy target to python.org and response with the content of http://python.org⁠

⁠Deployment

1. This project repository is https://bitbucket.org/austinjung/asyncproxyinpython⁠
2. The project repository is linked with Austin's Docker Cloud⁠
3. In your docker, run the following line.

   $ docker run -p 8080:8080 austinjung/async-http-proxy-python:latest
   

   Copy
   or

   clone the project repository
   cd /to/the_top_folder_of_the_project
   $ docker-compose up
   

   Copy

⁠Things do-to

1. Some images or contents are blocked by 'Referrer Policy: no-referrer-when-downgrade', 'Access-Control-Allow_Origin', or 'cross-origin frame' etc.
2. Do proper post method. and more
