Using the nocache Parameter

You can use the parameter nocache for the Service function send-file to specify that files in a certain directory are not cached. Make this change by editing obj.conf. For example, if you have a set of files that changes too rapidly for caching to be useful, you can put them into a directory and instruct the server not to cache files in that directory by editing obj.conf.
