# WRP - Web Rendering Proxy
|
|
|
|
A browser-in-browser "proxy" server that allows to use historical / vintage web browsers on the modern web. It works by rendering a web page in to a GIF or PNG image with clickable imagemap.
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
1. [Download a WRP binary](https://github.com/tenox7/wrp/releases/) and run it on a machine that will become your WRP gateway/server.
|
|
2. Point your legacy browser to `http://address:port` of WRP server. Do not set or use it as a "http proxy server".
|
|
3. Type a search string or a http/https URL and click **Go**.
|
|
4. Adjust your screen width/height/scale/#colors to fit in your old browser.
|
|
5. Scroll web page by clicking on the in-image scroll bar.
|
|
6. Do not use client browser history-back, instead use **Bk** button in the app.
|
|
7. To send keystrokes, fill **K** input box and press **Go**. There also are buttons for backspace, enter and arrow keys.
|
|
8. You can set height **H** to `0` to render pages in to one tall image without the vertical scrollbar. This feature is experimental and your mileage will vary depending ong many factors.
|
|
9. Prefer PNG over GIF if your browser supports it. PNG is much faster, whereas GIF requires a lot of additional processing on both client and server.

|
## Docker
|
|
|
|
docker hub:
|
|
|
|
```shell
|
|
docker run -d -p 8080:8080 tenox7/wrp
|
|
```
|
|
|
|
gcr.io:
|
|
|
|
```shell
|
|
docker run -d -p 8080:8080 gcr.io/tenox7/wrp:latest
|
|
```
|
|
|
|
## Flags
|
|
|
|
```flags
|
|
-l listen address:port, default :8080
|
|
-t image type gif (default) or png, when using PNG number of colors is ignored
|
|
-g image geometry, WxHXC, height can be 0 for unlimited, default 1152x600x256
|
|
-h headed mode, display browser window on the server
|
|
-d chromedp debug logging
|
|
-n do not free maps and gif images after use
|
|
```
|
|
|
|
## Minimal Requirements
|
|
|
|
* Server Gateway should run on a modern hardware/os that supports memory hungry Chrome.
|
|
* Client Browser needs to support `HTML FORMs` and `ISMAP`. Typically Mosaic 2.0 would be minimum version for forms. However ISMAP was supported since 0.6B, so if you manually enter url using `?url=...`, you can use the earlier version.
|
|
|
|
## Troubleshooting
|
|
|
|
### I can't get it to open
|
|
|
|
This program does not have a GUI and is run from the command line. You may need to enable executable bit, for example on Mac:
|
|
|
|
```bash
|
|
$ cd ~/your-download-directory
|
|
$ chmod +x wrp-amd64-macos
|
|
$ ./wrp-amd64-macos -t png
|
|
```
|
|
|
|
## History
|
|
|
|
* In 2014, version 1.0 started as a *cgi-bin* script, adaptation of `webkit2png.py` and `pcidade.py`, [blog post](https://virtuallyfun.com/2014/03/03/surfing-modern-web-with-ancient-browsers/).
|
|
* Later in 2014, version 2.0 became a stand alone http-proxy server, also support for both Linux/MacOS, [another post](https://virtuallyfun.com/wordpress/2014/03/11/web-rendering-proxy-update//).
|
|
* In 2016 the whole internet migrated to HTTPS/SSL/TLS and WRP largely stopped working. Python code became unmaintainable and mostly unportable (especially to Windows, even WSL).
|
|
* In 2019 WRP 3.0 has been rewritten in Golang/Chromedp as browser-in-browser instead of http proxy.
|
|
* Later in 2019, WRP 4.0 has been completely refactored to use mouse clicks via imagemap instead parsing a href nodes. Also in 4.1 added sending keystrokes in to input boxes. You can now login to Gmail. Also now runs as a Docker container. Version 4.5 introduces rendering whole pages in to one tall image image.
