Since we do not try to trick multiple IE versions to coexist, these native IE instances ensure optimal compatibility rendering fidelity and repeatability. At the core we use a proprietary C# application to control parallel rendering and to generate the virtual screenshot images. A separate frontend software does some pre-processing and error management, combines the image overlays and stores job logs and statistical data into an SQL database. For security reasons we must block Java and ActiveX, but Javascript is enabled. All machines will automatically receive Microsoft updates, so they should always be just as up-to-date as real-world browsers in the field.
