Abstract: Systems and methods are described for converting a resource from a first format that is normally rendered by a web browser using a file viewer that prevents monitoring user actions with respect to the resource on behalf of a proxy server into a second format that enables such monitoring. The proxy server injects code into a web page requested by the web browser to cause the web browser to mark a uniform resource locator (URL) of an element that is created by the web page. Upon detecting a request containing the marked URL, the proxy server examines the response corresponding to the request to determine if the response includes a resource in the first format. If the response includes a resource in the first format, the proxy server converts the resource into the second format and transmits the resource to the web browser in the second format.

Abstract: A tenant network of a cloud services platform performs the rewriting of code included in a web page. For example, a proxy service communicatively coupled to a plurality of browser applications belonging to the same tenant network and a server receives a request, from a first browser, for a web page hosted by the server. The web page is returned to the proxy service, and the proxy service identifies code component(s) thereof for rewriting. The proxy service provides the identified code component(s) to a second browser included in the same tenant network as the first browser that is configured to rewrite the code component(s). After rewriting the code component, the second browser provides the rewritten code component(s) to the proxy service, which forwards the web page, along with the rewritten code component(s), to the first browser for execution and rendering.
