I'm trying to accomplish two things with the new Headless Chrome:
1) import my existing Chrome cookies into Headless. Either using a similar technique to wget's "--save-cookies cookies.txt" or through some other means.
2) when I output the dom (using --dump-dom), I'd like the output not to overwrite the existing output file. I've been struggling with this for a while, and hoping someone can point me in the right direction!
