I personally do not see a problem here. Connect timeout is not much different than socket timeout. It is not an absolute value that defines a deadline for the operation. Like the socket timeout, which represents the maximum period of time between receipt of two consecutive IP packets, the connect timeout represents a maximum period of inactivity between two consecutive operations. For instance HttpClient will attempt to connect to all available DNS addresses for multi-home DNS entries which effectively makes the deadline for the connect operation equal n * connectTimeout (where n is the number of IP addresses for the DNS entry).
