i'm experiencing a problem with preconditions. í use the precondition of files to track the downloading of these. if i upload ppt's or doc's there aren't any problems. when i download i get one line in my logfile. if i download a pdf then the log shows 2 entries. to judge from the time the first is when the download starts an the secon when it ends.

anybod got an idea on why this is happening? With HTTP/1.1, clients can download parts of files and not only complete files. Such requests will tell the web server that they need a byte range and you will have a request for each range requested.

Apparently, only few clients make use of this new feature. Adobe Acrobat is one of them... Dieter
