# 01/xx/2003 Ron Fox.. Remove preforking. This makes the general daemon |
|
# logic simpler (and there were problems maintaining the preforked |
|
# population). Since the time averaged connection rate is close to zero |
|
# because lonc's purpose is to maintain near continuous connnections, |
|
# preforking is not really needed. |
|
# 08/xx/2003 Ron Fox: Add management requests. Management requests |
|
# will be validated via a call to ValidateManager. At present, this |
|
# is done by simple host verification. In the future we can modify |
|
# this function to do a certificate check. |
|
# Management functions supported include: |
|
# - pushing /home/httpd/lonTabs/hosts.tab |
|
# - pushing /home/httpd/lonTabs/domain.tab |
|
# 09/08/2003 Ron Fox: Told lond to take care of change logging so we |
|
# don't have to remember it: |
|
# $Log$ |
|
# Revision 1.144 2003/09/16 09:47:01 foxr |

# Added skeletal support for SIGUSR2 (update hosts.tab) |

# Revision 1.143 2003/09/15 10:03:52 foxr |

# Completed and tested code for pushfile. |

# Permanently store chatroom entries in chatroom.log |

# Revision 1.141 2003/09/08 10:32:07 foxr |

# Added PushFile sub This sub oversees the push of a new configuration table file |
|
# Currently supported files are: |
