 # 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/PNG/JPEG image associated with clickable imagemap of original web links. 
 
-New: Version 2.1 brings support for sslstrip to allow browsing https/SSL/TSL websites
+A HTTP proxy server that allows to use historical / vintage web browsers on the modern web. It works by rendering a web page in to GIF image with ISMAP.
 
+![Internet Explorer 1.5 doing Gmail](wrp.png)
 
-# Current Status
-* SSL/TLS stripping is delegated to `sslstrip`[1], which you need to install into your PATH first
-* I'm also looking for moving away from WebKit, QT and Python
-* Stay tuned
+## Current Status
 
-## OS Support
-WRP works on macOS (Mac OS X), Linux and FreeBSD. On macOS it uses Cocoa Webkit, on Linux/FreeBSD QT Webkit, for which needs PyQT4 or PyQT5.
+* This is a new version using GoLang/[ChromeDP](https://github.com/chromedp/chromedp) (Python/Webkit is now deprecated).
+* Fully supported an maintained.
+* Works as browser-in-browser. A real http proxy mode is being investigated. Check [issue #35](https://github.com/tenox7/wrp/issues/35) for updates.
+* Supports clicking on non-link elements (eg. cookie warnings, dropdown menus, etc.) and sending keystrokes. Yes, you can login to Gmail.
 
-## Installation
-* macOS - should just work
-* Linux/FreeBSD install `python-pyqt5.qtwebkit`
-* For sslstrip install `sslstrip`
-* For PythonMagick (Imagemagick library) install `python-pythonmagick`
+## Usage	
 
-## Configuration
-Edit wrp.py, scroll past Copyright section to find config parameters
+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 "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.
 
-## Usage 
-Configure your web browser to use HTTP proxy at IP address and port where WRP is running. If using browsers prior to HTML 3.2, ISMAP option may need to be enabled. Check configuration.
+## Docker
 
-## More info and screenshots
-* http://virtuallyfun.superglobalmegacorp.com/2014/03/11/web-rendering-proxy-update/
-* http://virtuallyfun.superglobalmegacorp.com/2014/03/03/surfing-modern-web-with-ancient-browsers/
+```
+docker run -d -p 8080:8080 --name wrp --restart unless-stopped tenox7/wrp
+```
 
-[1]: https://moxie.org/software/sslstrip/
+## Flags
+
+```
+-l  listen address:port, default :8080
+-h  headed mode, display browser window
+-d  chromedp debug logging
+```
+
+## 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 ealier version.
+
+## 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 instead using 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.
+
+## Credits 
+* Uses [chromedp](https://github.com/chromedp), thanks to [mvdan](https://github.com/mvdan) for dealing with my issues
+* Uses [go-quantize](https://github.com/ericpauley/go-quantize), thanks to [ericpauley](https://github.com/ericpauley) for developing the missing go quantizer
+* Thanks to Jason Stevens of [Fun With Virtualization](https://virtuallyfun.com/) for graciously hosting my rumblings
+* Thanks to [claunia](https://github.com/claunia/) for help with the Python/Webkit version in the past
