JavaScript Runtime Machine

We need to create a JavaScript Run machine or something very similar with the final objective of process HTTP Response with HTML that can fetch all dynamic objects of a Web page need to the initial load. Please, don’t think this is a simple HTML parser, you need to process and execute JavaScript to get dynamic objects. Pages like [login to view URL], [login to view URL], [login to view URL] and most of the important web pages, generate the DOM structure based in dynamic request like AJAX. We are implementing an HTTP Proxy and the problem to solve is basically process the HTTP Response with HTML that loads JS code included in HTML or in external files that once executed dynamically request more content to generate the initial web page. Requirements: - In order to really understand the problem you need to know very well how low level HTTP protocol works and be proficient in HTML/CSS/JavaScrip to know how Web Pages are loaded. - The Output of this job should be processed using Java, means that we need an API that we can use from Java. Doesn’t have to be native, but need an interface. You can use external piece of code of third parties. - Should be efficient enough, no need of any user interface, final objective is having the complete list of URI object (Images, Flash, and any external link) that are not in the initial HTML, needed for the first load of a web page after Dynamic data is loaded. Suggestions; You can use [login to view URL] in order to adapt the code for just execute the JavaScript. Remove all graphic interface. Also use code like Firefox Xulrunner or Chromium, however apps generate the WebPage and consume too much resources. INPUTS OF THE APPLICATION: Initial URL like [login to view URL] Outputs: Complete List of all external Object's URI (js, images, videos, Flash, JavaApplets, css) e.g.: [login to view URL] We will test this for pages mentioned above. PLEASE CONSIDER THAT IN ORDER TO PROCESS THE HTTP Response with the HTML, you would need to load and Run complex JavaScrip that will be executed in order to get Dynamic Content and Generate the Complete DOM of the Web Page.
