# 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 |
