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 -- Mehdi Sarmadi
