To expand: when clients browse to a directory, the webserver daemon has to generate a directory listing (usually sorted, which means the daemon has to retrieve the whole directory into memory, sort it, and then generate the HTML to send to the client). With large directories, that blocks that webserver process/thread for a noticable time. A relatively small number of requests can slow down and/or block other access. It would be possible to pre-generate the directory listings, maybe even dynamically regenerating them whenever the directories change, but that would add significant complication. Since the largest user of such a system is mirror servers (most "regular" webservers have directory listings disabled), and mirror servers represent a very small percentage of deployed webservers, nobody has done this. -- Chris Adams <cmadams@xxxxxxxxxx> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
