Abstract: A method, including defining rules for protecting sensitive data, each of the rules including a reference URL and a reference JSON data mapping to an item of the sensitive data in a JSON payload. A proxy receives, from an application executing on a host computer, a query including a URL for data hosted by a server, and forwards the URL to the server. The proxy receives, from the server, a response to the forwarded URL, the response including a set of values stored in respective mappings. The URL and the mappings in the response are compared to the rules; and upon detecting a match between a given rule and a combination including the URL and a given mapping in the response, the proxy anonymizes by the proxy, the value stored at the given mapping in the response, and forwards the response, including the anonymized value, to the software application.

Abstract: A method, including capturing, at a first time from an executing web-based application including browser-executable code, a first request including a first Uniform Resource Locator (URL) for a specified resource hosted by a first server, and conveying the request to the first server. Upon receiving, from the first server, the requested resource in response to the conveyed request, the received resource is stored to a second server referenced by a second URL different from the first URL. While executing the application at a second time subsequent to the first time, a second request for the specified resource is detected in the code. While the application is executing at the second time, the code is modified so as to reference the second URL, and the modified code is executed so as to convey the second request to the second URL.

Abstract: Methods, storage systems and computer program products implement embodiments of the present invention that include running by a web browser, a web-based application including a set of web pages, and identifying changes in the web pages rendered by the web browser while running the web-based application. For each identified change, a corresponding state of the web-based application is recorded, wherein the corresponding state includes browser-executable code for a given web page being rendered, and one or more transitions from the corresponding state to one or more other states is also recorded. The recorded states and the recorded transitions are compiled into a state machine model of the web-based application, and a demonstration of the application is generated using the state machine model.

Abstract: In embodiments of the present invention, a processor executing a web browser detects a first request including a Hypertext Transfer Protocol (HTTP) request conveyed by the web browser to a first server for a web page including browser-executable code for a web-based application, and a response received from the first server including the requested browser-executable code, wherein the first HTTP request includes a first Uniform Resource Locator (URL). In the browser-executable code, a second request to a second server for a web resource and including a second URL is identified, and the second URL in the browser-executable code is modified so as to reference a third server. The first URL is modified so as to reference a fourth server, and the modified browser-executable code is stored on the fourth server so as to be referenced by the modified first URL.
