WebView2 set cache size

Question

WebView2 set cache size

Pablo Glomby 186

I am using a webView2 control in .net and I want to limit the internal cache size but I am not finding the way...
It seems it's not documented.
I do for example:
CoreWebView2EnvironmentOptions options = new CoreWebView2EnvironmentOptions("--disk-cache-size-20000000");
...
var webView2Environment = await CoreWebView2Environment.CreateAsync(null, cacheFolderPath, options);
but it does not work.

Any idea?
Thanks.

@Pablo Glomby ,Based on my research, I also could not find the method to limit the cache size in webview2. There is a workaround to use call WebView.clearCache periodically to limits the effectiveness of the cache. You can refer to the link Has anyone successfully limited the size of their WebView's cache?. If the above workaround could not help you, I recommend that you could submit an issue in GitHub.

Hi Jack,
I think you may have confused with the Android's WebView control since WebView2 (Edge chromium Windows based control) does not have any clearCache method. Also the link you sent, refers to the Android WebView control.

Thanks

@Pablo Glomby , Sorry for that, I have realized the problem. Based on my further search, Currently I could not find the similar problem about the cache size in Edge. Therefore, It will be a good choice to submit an issue in GitHub. Thanks for understanding.
