A client with a Rails 2 app that displays games written in Flash is having
them converted to HTML5/Javascript. The team doing the conversions has no
problem reading the player's data with a Javascript function like this,
which I bound to a button click and ran with the Chrome debugging console
open:
> *function makeGetRequest() {*
> * var request = new XMLHttpRequest();** request.open('GET',
> <...url...>);*
>
> * // Response handler*
> * request.onload = function() {*
> * var text = request.responseText;*
> * console.log("responseText="+text)** };*
>
> * request.send();**}*
I have omitted the code to handle CORS (cross-origin resource sharing),
which is set in .htaccess on the server and does not seem to be a problem.
The following works in development to push data back to the Rails 2 app:
> *function makePutRequest() {*
> * var request = new XMLHttpRequest();** request.open('PUT',
> <...url...>);*
>
> * // Response handler*
> * request.onload = function() {*
> * var text = request.responseText;*
> * console.log("responseText="+text)** };*
>
> * request.setRequestHeader('Content-type', 'application/json');*
> * request.send('{"data":"this is updated data player data"}');**}*
but does not work in production. Changing 'PUT' to 'POST' and adding
* xhr.setRequestHeader('X-HTTP-Method-Override', 'PUT');*
also works in development but not in production.
The Chrome console says:
*XMLHttpRequest cannot load <...url...>. Invalid HTTP status code 405 *
The Rails 2 production log says:
> *Processing ApplicationController#index (for xx.xxx.xx.xxx at 2014-10-22
> 14:31:28) [OPTIONS]ActionController::MethodNotAllowed (Only get and put
> requests are allowed.):*

It got as far as actionpack, so why is production behaving badly but not
development? Is Apache/Passenger mangling the request before it gets there?
The app uses the latest version of Rails 2, ree-1.8.7, and Passenger,
hosted at RailsPlayground, where it has run without major problems for five
years.
I'm at a dead-end with Google. Anyone got an idea on what is the problem
here?
Thanks much, Scott
