    <p>I have created plugin for Mail.app on Mac OS. I'm using WebView to display web pages, all would be fine but web pages load slowly.</p> <p>Then I created test cocoa application to compare loading time. I was surprised when the test application loads page ~5 times faster.</p> <p>In developer bar I saw my test application receives <a href="http://www.checkupdown.com/status/E304.html" rel="nofollow">304 code</a> that indicates "the resource for the requested URL has not changed and cached resource can be used". In contrast to the test application the plugin always receives 200 http code and loads resource again.</p> <p>Maybe I should specify to use a cache in the webview, or I have some bundle permissions problems.</p> <p>In the plugin, I tried to specify <code>SharedURLCache</code> like this</p> <pre><code>NSURLCache *cache = [[NSURLCache alloc] initWithMemoryCapacity:1024*1024*20 diskCapacity:1024*1024*5 diskPath:NSHomeDirectory()]; [NSURLCache setSharedURLCache:cache]; </code></pre> <p>Then I tried subscribe to the <code>ResourceLoadDelegate</code> on the WebView and change request object like this</p> <pre><code>- (NSURLRequest *)webView:(WebView *)sender resource:(id)identifier willSendRequest:(NSURLRequest *)request redirectResponse:(NSURLResponse *)redirectResponse fromDataSource:(WebDataSource *)dataSource { if ([request cachePolicy] != NSURLRequestReturnCacheDataElseLoad) { return [NSURLRequest requestWithURL:[request URL] cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:[request timeoutInterval]]; } else { return request; } } </code></pre> <p>Also I tried to change properties on WebView</p> <pre><code>[[webView preferences] setUsesPageCache:YES]; [[webView preferences] setCacheModel:WebCacheModelPrimaryWebBrowser]; </code></pre> <p>but it's all not working.</p> <p>Thanks for help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
