Abstract

An intermediary server provides secure access to a web page of a web-based service upon request of a web server. The intermediary server includes an operating system that runs a new instance of a web browser engine. The web browser engine creates a temporary folder to isolate the new instance from other instances and deletes the temporary folder upon deletion of the new instance. The web browser engine produces an image of a web page rendered in the new instance and transmits an access web page to a web browser. The access web page is configured to retrieve the image from the web browser engine and display the image in the web browser. User interactions are registered and sent to the new instance in the intermediary server. The user interactions are reproduced within the new instance and the new instance produces images of the web page after the user interactions.
