For example, if you are accessing a url like: `https://example.com/styled/basic/sprites/icon_spritemap.css` To force the browser to fetch the updated version, you would append the following: `https://example.com/styled/basic/sprites/icon_spritemap.css?` **Note** The application that updates the resource at this url on the server **must** call the `CacheBuster::update` function when it updates the resource to signify that update.' operationId: CacheBuster-read parameters: [] responses: '200': content: application/json: schema: properties: apiversion: description: The version of the API. example: 3 type: integer func: description: The name of the method called. example: read type: string module: description: The name of the module called. example: CacheBuster type: string result: properties: data: properties: cache_id: description: An eight-digit random integer that the system uses to work around a browser's caching mechanism. example: 11381138 maximum: 99999999 minimum: 10000000 type: integer type: object errors: description: List of errors if the API failed. example: null items: type: string type: - array - 'null' messages: description: List of messages generated by the API. example: null items: type: string type: - array - 'null' metadata: properties: {} status: description: '* `1` — Success. * `0` — Failed.
