WebView not reflecting changes on server until clearing data

I found an interesting bug that I can not replicate, but think someone here could provide some insight.

I have an activity that for now is partially native, partially web-based. By that I mean one element is simply a WebView until implementation on a native level can be achieved.

When I made a change in the page I am loading, I saw an immediate change using Chrome Developer Tools in a mobile interface. However, I was unable to immediately see the change in my WebView in my MainApp. As a test, I installed a new app that loaded the page in a WebView where I saw the changes. After clearing the data in my MainApp, I was able to see said changes.

I made a few more changes, but now these are being reflected immediately in my WebView (upon backing out of the activity and re-entering).

These are my WebView settings, can you see a reason for me not initially seeing these changes? I'm not very savvy (yet :) ) when dealing with how data is stored in a WebView and want to ensure that updates I make to my webpage are reflected immediately in the app. Thank you!

// Initialize WebView
    if (Build.VERSION.SDK_INT >= 19)
        mWebView.setWebContentsDebuggingEnabled(false);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);

            // Hide ProgressBar
            mProgressBar.setVisibility(View.GONE);
        }
    });
    final ActionBarActivity activity = this;
    mWebView.setWebChromeClient(new WebChromeClient() {
        public void onProgressChanged(WebView view, int progress) {
            // Activities and WebViews measure progress with different scales.
            // The progress meter will automatically disappear when we reach 100%
            mProgressBar.setProgress(progress);
        }
    });

    // Settings for WebView data
    WebSettings ws = mWebView.getSettings();
    ws.setSaveFormData(false);
    ws.setSavePassword(false); // Not needed for API level 18 or greater (deprecated)

In case if you want to reload the the webview every time when you reopen.

use this setting for webview

webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);

This will not load the cache and the requirement will get fulfilled.

You probably need to disable the cache for your webview. When your data changes you need to reload the webview using mWebView.reload()
