It does not 34// impact the HTTP request headers. 35LOAD_FLAG(DISABLE_CACHE, 1 << 5) 36 37// This is a navigation that will not be intercepted by any registered 38// URLRequest::Interceptors. 39LOAD_FLAG(DISABLE_INTERCEPT, 1 << 6) 40 41// If present, upload progress messages should be provided to initiator. 42LOAD_FLAG(ENABLE_UPLOAD_PROGRESS, 1 << 7) 43 44// If present, ignores certificate mismatches with the domain name. 45// (The default behavior is to trigger an OnSSLCertificateError callback.) 46LOAD_FLAG(IGNORE_CERT_COMMON_NAME_INVALID, 1 << 8) 47 48// If present, ignores certificate expiration dates 49// (The default behavior is to trigger an OnSSLCertificateError callback). 50LOAD_FLAG(IGNORE_CERT_DATE_INVALID, 1 << 9) 51 52// If present, trusts all certificate authorities 53// (The default behavior is to trigger an OnSSLCertificateError callback). 54LOAD_FLAG(IGNORE_CERT_AUTHORITY_INVALID, 1 << 10) 55 56// If present, causes certificate revocation checks to be skipped on secure 57// connections. 58LOAD_FLAG(DISABLE_CERT_REVOCATION_CHECKING, 1 << 11) 59 60// If present, ignores wrong key usage of the certificate 61// (The default behavior is to trigger an OnSSLCertificateError callback). 62LOAD_FLAG(IGNORE_CERT_WRONG_USAGE, 1 << 12) 63 64// This load will not make any changes to cookies, including storing new 65// cookies or updating existing ones. 66LOAD_FLAG(DO_NOT_SAVE_COOKIES, 1 << 13) 67 68// Do not resolve proxies.
