# 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. |

Pushes a file in /home/httpd/lonTab directory. Currently limited to: |
|
hosts.tab and domain.tab. The old file is copied to *.tab.backup but |
|
must be restored manually in case of a problem with the new table file. |
|
pushtable requires that the request be encrypted and validated via |
|
ValidateManager. The form of the command is: |
|
enc:pushtable tablename <tablecontents> \n |
|
where pushtable, tablename and <tablecontents> will be encrypted, but \n is a |
|
cleartext newline. |
