title: How do I manually clear cache for webview in Chrome app?
body: <p>I am developing a Chrome app that shows some web content in a webview tag. The content is being cached. When I edit the content files, clearing Chrome browsers' cache does not seem to actually clear the webview cache.</p>
  
  <p>One of the posts recommends to assign a unique partition ID every time Chrome app starts.
  Changing partition ID on the webview does help to clear (or re allocate) the cache, but I still would like to take advantage of caching 3MB of web content and clear it manually only if it changes.</p>
  
  <p>Is there a way to clear that cache, in particular on Chrome OS?</p>
