RequestContextSettings Properties

Comma delimited ordered list of language codes without any whitespace that will be used in the "Accept-Language" HTTP header. Can be set globally using the CefSettings.accept_language_list value or overridden on a per- browser basis using the BrowserSettings.AcceptLanguageList value. If all values are empty then "en-US,en" will be used. This value will be ignored if CachePath matches the CefSettings.CachePath value.

The location where cache data for this request context will be stored on disk. If non-empty this must be either equal to or a child directory of CefSettings.RootCachePath. If empty then browsers will be created in "incognito mode" where in-memory caches are used for storage and no data is persisted to disk. HTML5 databases such as localStorage will only persist across sessions if a cache path is specified. To share the global browser cache and related configuration set this value to match the CefSettings.CachePath value.

Set to true to enable date-based expiration of built in network security information (i.e. certificate transparency logs, HSTS preloading and pinning information). Enabling this option improves network security but may cause HTTPS load failures when using CEF binaries built more than 10 weeks in the past. See https://www.certificate-transparency.org/ and https://www.chromium.org/hsts for details. Can be set globally using the CefSettings.EnableNetSecurityExpiration value.

Set to true to ignore errors related to invalid SSL certificates. Enabling this setting can lead to potential security vulnerabilities like "man in the middle" attacks. Applications that load content from the internet should not enable this setting. Can be set globally using the CefSettings.IgnoreCertificateErrors value. This value will be ignored if CachePath matches the CefSettings.cache_path value.

To persist session cookies (cookies without an expiry date or validity interval) by default when using the global cookie manager set this value to true. Session cookies are generally intended to be transient and most Web browsers do not persist them. Can be set globally using the CefSettings.PersistSessionCookies value. This value will be ignored if CachePath is empty or if it matches the CefSettings.CachePath value.

To persist user preferences as a JSON file in the cache path directory set this value to true. Can be set globally using the CefSettings.PersistUserPreferences value. This value will be ignored if CachePath is empty or if it matches the CefSettings.CachePath value.
