Thanks very much.. I checked my Apache books and googled around, but I could not find anything anyhere about TransferLog for directories. But am/was not sure if I had missed something.

Rewrite is some magic I recently discovered. It seems adepts can make it do almost anything. Not me yet though..

hmm.. those ideas could be worth testing.

Right. That's what I started writing last night ;-) Used a 5Mb current access_log file to test and started building a tool in /View to search for string [folder name] and by date. I was very impressed by how quick it is :-) Fast to run and to write. ...except for the lack of better /View docs >:-(( One problem I see now is that for remote client reblet use, I still need to pre-process my log file on the server, else the download data size is too big. Another is that searching the Apache request paths could be unerailable. Hopefully c\seom common sense rules-of-thumb can offset that. Anyway, I found some starter code in 'REBOL for Dummies', which I've come to appreciate more and more. It's the only book in that series I own. Clear simple with some useful stuff sometimes not covered in the other REBOL books. Here's the main function: log-file: %access_log_sample.txt search-log: func [keyword ][ result: copy "" accesslog: open/direct/read/lines log-file while [(line: pick accesslog 1) <> none ][ if (find line keyword) [ append result rejoin [line newline] ] ] close accesslog return result ] and a little tool for the dates so they can be passed as keywords also ;; convert dates to format used in Apache logs so we can search them also: 18/Jun/2002 to-logdate: func [adate [date!]][ monthname: pick ["Jan" "Feb" "Mar" "Apr" "May" "Jun" "Jul" "Aug" "Sep" "Oct" Nov "Dec"] adate/month d: copy "" append d rejoin [adate/day "/" monthname "/" adate/year] return d ] I'll post the reblet when it stabilizes and gets some more mature features. ./Jason
