I had a quick look at the PR - do you mind adding a small test, @kugg ?

Hi I checked the docs and realized I was far from compliant. I updated the supported functions to follow syntax and added a testcase for each cmd. The structure used today allow for expansion of the other command using the header(Cookie) value as a "array compatible list".
