|
|
# of that is returned. If not, then the routine attempts to construct
|
|
# the URI from other parts of the hash. The values of the 'port' and 'path'
|
|
# keys are used directly from the hash. For the host, if the
|
|
# 'bind_interface' key is non-nil then it will use the first IP address on
|
|
# the specified interface, otherwise it will use the value of the 'host' key
|
|
# from the hash.
|
|
#
|
|
# Returns nil if the 'uri' key does not exist in the supplied hash and if
|
|
# the determined host is nil (both the values of the 'bind_interface' and
|
|
# 'host' keys are nil).
