Well, the title says it all... It is possible to perform an XmlHttpRequest from Selenium/Webdriver and then render the output of that requests in a browser instance ? If so, can you enlight me please ?
One option would be to make the XHR request using, for instance, requests, save the response to a file and get() it with selenium webdriver instance (How to use selenium webdriver on local (on my pc) webpage instead of locate somwhere on www?).
