## Do cookies work in Cordova apps?

The rules for cookies in the Cordova apps the same as everywhere. You should not expect your app to be able to persist cookies for its own use, because generally speaking Cordova applications aren't backed by a web server and thus have no place to store cookies. Most Cordova platforms serve files from the `file:///` protocol, and thus subject to standard browser security rules. This is means that non-GET requests whould be subject to CORS and preflight OPTIONS request would be issued for POST and other verbs. Good exaplanations about CORS and Cordova app could be found [here] ( In case you don't heard about CORS, you could start reading about [CORS on HTML5Rocks](

## How to work with cookies in Cordova apps?

There are two ways in which you may want to use cookies. The first is within XHR (Ajax) requests to remote resources. Unless you specifically remove them, your Ajax library will automatically use cookies in subsequent calls to remote APIs and resources you request. So given that some API returns a cookie required for future calls, you can assume it will be automatically sent when your app hits it again.

The other way your app may desire to use cookies is locally - ie within the app itself. This does not make sense within a Cordova app as it isn't running on a proper web server itself. If your intent is simply to store data for the app then you should make use the various [existing methods]( to store data locally.
