Region Commands
The Negotiation command overrides for specified regions any global
specifications set for the same items by the Negotiation directive. For further
information about using the Negotiation directive, see Negotiation on
page A-38.
NoCache
The NoCache directive is used to disable file caching for all URLs matching the
URL_path. In other words, none of the file opens, file stats, or file contents in the
region are cached.
The file caching mechanism is applied to all disk files on an iTP Secure
WebServer. If a small number of disk files require constant updates, frequent
updates to the file cache might also be required, and this might impact the overall
performance of the iTP Secure WebServer. The NoCache Region command can
be used to exclude some of these files from file caching and allow the static files to
remain in the cache longer, and therefore help maintain a good performance.
However, the Region directive is evaluated for every request and, in this case,
every file access. Therefore, too many Region directives might also affect the
efficiency of the iTP Secure WebServer. It might be best to keep all constantly
updated files in a single region.
When no Region directive or no NoCache command in the Region directives is
present, the server attempts to cache all files accessed.
For example:
Region /h/dynamic_files/* {
NoCache
}
NoLog
The NoLog command disables logging for the current request. No entry is made in
the server access log, error log, or extended log files.
For example, the following command disables logging for all files ending with a
.gif extension:
Region *.gif {
NoLog
}
OutputTimeout time-in-seconds
The OutputTimeout command sets the time (in seconds) that the iTP Secure
WebServer is to spend sending a requested file to a Web client. If the entire file
has not been sent within this limit, the request is canceled and the connection is
closed. The default value is 1200 seconds (20 minutes). The maximum value is
4294967295 (the maximum value permitted for an unsigned long integer).
