> It would be super cool if I could write Javascript in a web page to read/write my Phoenix tables.  I spend the last few days learning about CORS and browser security.  I found out that what I am trying to accomplish cannot be readily done because the browser adds CORS headers (like {color:blue}{{Origin: <whatever>}}{color}) and methods (like {color:blue}{{method: OPTIONS}}{color}) that are not supported by Phoenix Query Server.
> I do not know if this can be added on the Phoenix side or if it has to be added on the Avatica side, but for the time being I am trying the following to make it work:
> 1.  Unconventional Javascript to remove the {color:blue}{{X-Requested-With}}{color} header in the request.
> 2.  One line code change in Avatica's {color:blue}{{AvaticaJsonHandler.handle()}}{color} to add an {color:blue}{{Access-Control-Allow-Origin: *}}{color} header to the response.
