#Introduction

This framework can be used to run lagacy web applications designed to be working only in Internet Explorer (Version 8 or lower) on other browsers. This is done by rewriting parts of the application on the fly as it's bytes pass the wire. The framework acts as proxy server, which get's requests by the browser, transforms them if needed and rewrites the results of such requests to make them understandable to modern browsers.

• Rewrite request URLs on the fly
• Rewrite response headers and content on the fly
  • Rewrite contents using regular expressions
  • Rewrite JavaScript based on AST

This framework need just Java (Version 1.6 or higher) as runtime environment, to check out and compile you also need Git, Maven and a internet connection to resolve required artifacts.

Just run the following command to get a copy of the source code:

git clone https://github.com/christianmahnke/lbs4-proxy.git

To build a packaged version just run:

mvn package

To run the proxy directly from sources just call:

mvn clean compile exec:exec

Configuration is done via Spring, see src/main/resources/beans.xml. You can set the port the proxy listens to and the filter options there.

To use the proxy server you need to point your browser to it, this is done in the network settings of your browser, without changes to the configuration of the proxy it listens to localhost:8080.

Currently the proxy allows one to log into the LBS4 Client, seletion of the requested subsystem and shows the counter if the OUS module is selected.
