Additional keyword parameters are used to configure attributes of the connection. Accepted parameters include: - ``source_address``: Set the source address for the current connection. - ``socket_options``: Set specific options on the underlying socket. If not specified, then defaults are loaded from ``HTTPConnection.default_socket_options`` which includes disabling Nagle's algorithm (sets TCP_NODELAY to 1) unless the connection is behind a proxy. For example, if you wish to enable TCP Keep Alive in addition to the defaults, you might pass: .. code-block:: python HTTPConnection.default_socket_options + [ (socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1), ] Or you may want to disable the defaults by passing an empty list (e.g., ``[]``). r2 ztyping.ClassVar[int]� default_portr z0typing.ClassVar[connection._TYPE_SOCKET_OPTIONS]�default_socket_optionsF�bool� is_verifiedNz bool | None�proxy_is_verified�int� blocksizeztuple[str, int] | None�source_addressz&connection._TYPE_SOCKET_OPTIONS | None�socket_options�_has_connected_to_proxyz_ResponseOptions | None�_response_optionsz str | None� _tunnel_hostz int | None� _tunnel_port�_tunnel_schemei @ )r r< r; r= �proxy� proxy_config�strr z&None | connection._TYPE_SOCKET_OPTIONSz Url | NonezProxyConfig | None�None) �host�portr r< r; r= rC rD �returnc sP t � j||t�|�||d� || _|| _|| _d| _d | _d | _ d | _ d | _ d S )N)rG rH r r< r; F) �super�__init__r Zresolve_default_timeoutr= rC rD r> r? r@ rA rB ) �selfrG rH r r< r; r= rC rD )� __class__r r rK � s zHTTPConnection.__init__)rI c C s | j �d�S )a� Getter method to remove any trailing dots that indicate the hostname is an FQDN. In general, SSL certificates don't include the trailing dot indicating a fully-qualified domain name, and thus, they don't validate properly when checked against a domain name that includes the dot. In addition, some servers may not expect to receive the trailing dot when provided. However, the hostname with trailing dot is critical to DNS resolution; doing a lookup with the trailing dot will properly only resolve the appropriate FQDN, whereas a lookup without a trailing dot will search the system's search domain list. Thus, it's important to keep the original host around for use only in those cases where it's appropriate (i.e., when doing DNS lookup to establish the actual TCP connection across which we're going to send HTTP requests). �.)� _dns_host�rstrip)rL r r r rG � s zHTTPConnection.host)�valuerI c C s || _ dS )z� Setter for the `host` property.
