gophper-proxy is a simple web proxy for gopher servers. It should run on any modernish PHP server, and most of the processing is actually done in javascript for maximum portability. There's also a docker setup which can run anywhere that docker works.

• It runs on PHP using [Slim][slim], which is a nifty lightweight application framework.
• It caches requests for faster response times.
• All of the rendering happens in the browser, which means someone could easily write a different backend.
• If the user accesses a binary file, they can download it. If they click on an image, they can see it in the browser.
• You can restrict it to a single gopher server, so you can integrate it into your project without any fears of someone using your proxy for naughty tricks.

The docker image is built from a PHP/apache image, so running it is pretty simple. Something like this should work:

docker build -t gophper-proxy .
docker run -it --rm --name my-running-app gophper-proxy

There are a few environment variables you can use to configure the proxy:

• GOPHER_TITLE: The title which will be used when outputting pages
• START_REQUEST: An initial server to load requests from. If not specified, a stock intro page is used. Example: gopherpedia.com:70
• RESTRICT_TO_MATCH: A filter to restrict which pages can be served. For example, to restrict to a single server you could use something like /gopherpedia.com/
• ALLOW_ALL_PORTS: true or false. Should the proxy allow ports other than 70? Setting this to true is a security risk.

Here's a sample `docker-compose.yml' file if that's helpful for you:

version: "3.5"

services:
  web:
    image: muffinista/gopher-proxy
    networks:
      - external_network
    env_file: .env
    environment:
      docker: "true"
      production: "false"
    volumes:
      - .:/var/www/html #:cached
      - ./logs:/var/www/logs:cached
    ports:
      - 80:80
networks:
  external_network:

• Copy the code to your web tree
• Set any environment variables that are needed (see above)
• Copy config.php.example to config.php, and double-check the variables for anything you might need to set. In particular, you need to create a cache directory and make sure it is writable.
