href="qwebengineurlrequestinterceptor.html">QWebEngineUrlRequestInterceptor</a> interface and installing the interceptor on the profile enables intercepting, blocking, and modifying URL requests before they reach the networking stack of Chromium.</p> <p>You can install the interceptor on a profile via <a href="qwebengineprofile.html#setRequestInterceptor">QWebEngineProfile::setRequestInterceptor</a>() or <a href="qquickwebengineprofile.html#setRequestInterceptor">QQuickWebEngineProfile::setRequestInterceptor</a>().</p> <p>When using the <a href="qtwebengine-overview.html#qt-webengine-widgets-module">Qt
