Detailed Description

QWebEngineClientHints allows configuration of exposing browser and platform information via User-Agent response and request headers, and a JavaScript API.

The information accessed via this API is split into two groups: low entropy and high entropy hints. Low entropy hints (platform and mobile) are those that do not give away much information; the API makes these accessible with every request and they can not be disabled by QWebEngineClientHints::setAllClientHintsEnabled.

All the others are high entropy hints; they have the potential to give away more information, therefore they can be disabled by QWebEngineClientHints::setAllClientHintsEnabled.

Each profile object has its own QWebEngineClientHints object, which configures the Client Hint settings for that browsing context. If a Client Hint is not configured for a web engine profile, its default value is deduced from the system.

See also QWebEngineProfile::clientHints() and QQuickWebEngineProfile::clientHints().

Property Documentation

arch : QString
