The following metrics will be set to nil, if a persistent connection was used or the resource was retrieved from local resources: domainLookupStartDate domainLookupEndDate connectStartDate connectEndDate secureConnectionStartDate secureConnectionEndDate

      • isProxyConnection

        public boolean isProxyConnection()
        This property is set to YES if a proxy connection was used to fetch the resource.

      • isReusedConnection

        public boolean isReusedConnection()
        This property is set to YES if a persistent connection was used to fetch the resource.

        public java.lang.String networkProtocolName()
        The network protocol used to fetch the resource, as identified by the ALPN Protocol ID Identification Sequence [RFC7301]. E.g., h2, http/1.1, spdy/3.1. When a proxy is configured AND a tunnel connection is established, then this attribute returns the value for the tunneled protocol. For example: If no proxy were used, and HTTP/2 was negotiated, then h2 would be returned. If HTTP/1.1 were used to the proxy, and the tunneled connection was HTTP/2, then h2 would be returned. If HTTP/1.1 were used to the proxy, and there were no tunnel, then http/1.1 would be returned.

      • requestEndDate

        public NSDate requestEndDate()
        requestEndDate is the time immediately after the user agent finished requesting the source, regardless of whether the resource was retrieved from the server or local resources. For example, this would correspond to the time immediately after the user agent finished sending the last byte of the request.

      • requestStartDate

        public NSDate requestStartDate()
        requestStartDate is the time immediately before the user agent started requesting the source, regardless of whether the resource was retrieved from the server or local resources. For example, this would correspond to the time immediately before the user agent sent an HTTP GET request.

        Indicates whether the resource was loaded, pushed or retrieved from the local cache.

      • response

      • responseStartDate

        public NSDate responseStartDate()
        responseStartDate is the time immediately after the user agent received the first byte of the response from the server or from local resources. For example, this would correspond to the time immediately after the user agent received the first byte of an HTTP response.

      • secureConnectionEndDate

        public NSDate secureConnectionEndDate()
        If an encrypted connection was used, secureConnectionEndDate is the time immediately after the security handshake completed. If an encrypted connection was not used, this attribute is set to nil.

      • secureConnectionStartDate

        public NSDate secureConnectionStartDate()
        If an encrypted connection was used, secureConnectionStartDate is the time immediately before the user agent started the security handshake to secure the current connection. For example, this would correspond to the time immediately before the user agent started the TLS handshake. If an encrypted connection was not used, this attribute is set to nil.
