WRP - Web Rendering Proxy

A HTTP proxy server that allows to use historical and obsolete web browsers on the modern web. It works by rendering the web page in to a GIF image with ISMAP.

Current Status

• This is a new version using GoLang/ChromeDP. Python/Webkit being now deprecated.
• Beta versiom, but fully supported an maintained.
• Works as browser-in-browser. A real http proxy mode is being investigated. Check issue #35 for updates.
• As of 4.1 supports clicking on non-link elements (eg. cookie warnings, dropdown menus, etc.) and sending keystrokes. Yes, you can login and use Gmail.

Usage

1. Download a WRP binary and run it on a machine that will become your WRP server.
2. Point your legacy browser to http://address:port of WRP server. Do not set or use it as a "Proxy Server" (yet).
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 WRP button.
7. To send keystrokes fill K input box and press Go. There also are buttons for backspace, enter and arrow keys.

Flags

-l  listen address:port, default :8080
-h  headed mode, display browser window
-d  chromedp debug logging

Minimal Requirements

WRP Server / Gateway should run on a modern hardware/os that supports memory hungry Chrome.

WRP Client / Browser needs to support forms and ISMAP. Typically Mosaic 2.0 would be minimum version for forms, although ISMAP was supported since 0.6B so you could manually enter url using ?url=....

History

• In 2014, version 1.0 started as a cgi-bin script, adaptation of webkit2png.py and pcidade.py, blog post.
• Later in 2014, version 2.0 became a stand alone http-proxy server, also support for both Linux/MacOS, another post.
• 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 instead using a href nodes. Also in 4.1 added sending keystrokes in to input boxes. You can now login to Gmail.
