Value Condition
auto

Disables caching for stream or ms-stream data.
enabled

Enables caching for stream or ms-stream data.

Remarks

By not caching data streamed using XHR, you can get better battery life on tablets and laptops, and avoid disk latency bottlenecks. To get the current caching state, use msCachingEnabled.

Examples

This example shows how to force caching for a stream of data.

        var xhr = new XMLHttpRequest();
        xhr.open('GET', url, true);
        xhr.msCaching = 'enabled';  
        xhr.responseType = 'stream';  
        xhr.send();
