How do you clear the WebView cache in Cocoa?

cocoa, macos, webview

Solution

The other suggested solutions didn't work for the local stylesheet (though they should work for remote resources).

I finally managed to solve this via the resourceLoadDelegate, by explicitly setting the cache policy:

- (NSURLRequest *)webView:(WebView *)sender resource:(id)identifier willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)redirectResponse fromDataSource:(WebDataSource *)dataSource {
    request = [NSURLRequest requestWithURL:[request URL] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:[request timeoutInterval]];
    return request;
}

Fun stuff.

Problem

How do you clear/flush the WebView cache in a Cocoa app? In particular, I would like to clear the cache of a local stylesheet. I have tried the following to no avail: ``` // Tried this before loadRequest [[NSURLCache sharedURLCache] removeAllCachedResponses]; // Also tried this before and after loadRequest [webView.mainFrame reloadFromOrigin]; ``` Even replacing the `WebView` with a new one still uses the cached stylesheet.
