This bug report originated from issue QTBUG-4839
http://bugreports.qt.nokia.com/browse/QTBUG-4839

--- Description ---

The following example (whole example in the attachment) will load the page from
the network even if QNetworkRequest::AlwaysCache is set. the documentation says
"only load from cache, indicating error if the item was not cached (i.e.,
off-line mode)":

<div class="code panel" style="border-width: 1px;"><div class="codeContent
panelContent">
<pre class="code-java">QWebPage *webPage = ui->webView->page();
QNetworkAccessManager *netAccessMgr = <span class="code-keyword">new</span>
QNetworkAccessManager(<span class="code-keyword">this</span>);
QNetworkDiskCache *dc = <span class="code-keyword">new</span>
QNetworkDiskCache(<span class="code-keyword">this</span>);
dc->setCacheDirectory(<span class="code-quote">"cache"</span>);
netAccessMgr->setCache(dc);
webPage->setNetworkAccessManager(netAccessMgr);

QNetworkRequest *request = <span class="code-keyword">new</span>
QNetworkRequest(QUrl(ui->lineEdit->text()));
request->setAttribute(QNetworkRequest::CacheLoadControlAttribute,
QNetworkRequest::AlwaysCache);
ui->webView->load(*request);</pre>
</div></div>

--- Comments ---

Do we have an AlwaysCache autotest?

Yes, we do have a test. This is not a QNetworkAccessManager issue. It's a
QWebFrame issue, that doesn't honour the attributes set in the request.

PS: your sample code leaks the QNetworkRequest. Don't use "new".
