[det]http_logrotate(+Options)Rotate the available log files. Note that there are two ways to deal 
with the rotation of log files:
- Use the OS log rotation facility. In that case the OS must (1) move 
the logfile and (2) have something calling
http_log_close/1 to close 
the (moved) file and make this server create a new one on the next log 
message. If
library(http/http_unix_daemon) is used, closing is achieved 
by sending SIGHUP or SIGUSR1 to the process. 
- Call this predicate at scheduled intervals. This can be achieved by 
calling http_schedule_logrotate/2 
in the context of 
library(http/http_unix_daemon) which 
schedules the maintenance actions. 
Options:
- min_size(+Bytes)
 - Do not rotate if the log file is smaller than Bytes. The 
default is 1Mbytes.
 
- keep_logs(+Count)
 - Number of rotated log files to keep (default 10)
 
- compress_logs(+Format)
 - Compress the log files to the given format.
 
- background(+Boolean)
 - If 
true, rotate the log files in the background.
