[squid-users] Content-Length and range header

Everyone

  How could I define an acl for multipart file download or big
filesize download?

  At the first look, It seems I need sth like this:
  acl lessthan3MB rep_header Content-Length ^(1|2)?+[0-9]{0,6}?$
  acl multiparts rep_header range [0-9]+

  Could I use them so? Am I in the right way?
  What are your oppinions?

TIA
Best Regards
