[mirrorbrain-commits] [mod_asn] r65 - trunk

Author: poeml

New Revision: 65
URL: http://svn.mirrorbrain.org/viewvc/mod_asn?view=revision&revision=65

Log:
asn_get_routeviews:
- The logic which decided whether to downlaod the routing data snapshot file was fixed.
  If the script is called and it finds a file which was downloaded less then 8
  hours ago, the file is reused. If no file exists or the file is older than 8 hours,
  it is downloaded again.
