NAME - look up URLs in Cache Digests


  echo | -duv 3128 -h saved-digest < old-access-log
  zcat old-access-log.gz | -v saved-digest


This program lets you look up URLs (the HTTP 'GET' method is assumed) in Cache Digests which are either fetched via HTTP or loaded from a file. The list of URLs should be supplied via STDIN, and can be in Squid log file format (the default), or simply a list of URLs (when the -u argument is supplied).



Debug mode - causes helpful debugging messages to be printed


Print the Digest header details out, e.g. version number and number of URLs in Digest, then exit.


Input is a list of URLs rather than Squid log file format.


Verbose mode - causes each URL being looked up to be printed to STDOUT, along with a hit/miss indicator.
