The non-interactive network downloader
Consider "connection refused" a transient error and try again. Normally Wget gives up on a URL when
it is unable to connect to the site because failure to connect is taken as a sign that the server is
not running at all and that retries would not help. This option is for mirroring unreliable sites
whose servers tend to disappear for short periods of time.
If you don't want Wget to wait between every retrieval, but only between retries of failed downloads,
you can use this option. Wget will use linear backoff, waiting 1 second after the first failure on a
given file, then waiting 2 seconds after the second failure on that file, up to the maximum number of
seconds you specify.
By default, Wget will assume a value of 10 seconds.
Set the read (and write) timeout to seconds seconds. The "time" of this timeout refers to idle time:
if, at any point in the download, no data is received for more than the specified number of seconds,
reading fails and the download is restarted. This option does not directly affect the duration of
the entire download.
Of course, the remote server may choose to terminate the connection sooner than this option requires.
The default read timeout is 900 seconds.
Set the network timeout to seconds seconds. This is equivalent to specifying --dns-timeout,
--connect-timeout, and --read-timeout, all at the same time.
When interacting with the network, Wget can check for timeout and abort the operation if it takes too
long. This prevents anomalies like hanging reads and infinite connects. The only timeout enabled by
default is a 900-second read timeout. Setting a timeout to 0 disables it altogether. Unless you
know what you are doing, it is best not to change the default timeout settings.
All timeout-related options accept decimal values, as well as subsecond values. For example, 0.1
seconds is a legal (though unwise) choice of timeout. Subsecond timeouts are useful for checking
server response times or for testing network latency.
Set number of retries to number. Specify 0 or inf for infinite retrying. The default is to retry 20
times, with the exception of fatal errors like "connection refused" or "not found" (404), which are
