of service and attempted buffer overflow attacks by restricting the effect of malicious requests that
contain unusually large payload entities. If the server detects a posted request longer than this
value, it sends an error response to the client and logs details of the attempted request.
Default: 131072
A-2-15 server.http.log.reverseDNS
This property determines whether the Device Manager server performs reverse-DNS lookup for its
access logging. If this property is set to true, the host name is determined from a given IP address.
If DNS can find the name of the host associated with the IP address, the host name is also written
into the access log. If DNS cannot find the name or this property is set to false, the IP address is
written into the access log.
NOTE: While translation of the IP address to a domain name can assist analysis of the server's
access logs, reverse-DNS lookups are expensive in terms of resources, and this feature may
significantly degrade the server's performance, especially on a slow network. You should keep the
setting at the default value for better performance.
Default: false
A-2-16 server.http.cache.size
This property sets the upper-limit size of the Device Manager server's internal file cache in bytes. A
value of 0 turns file caching off, which may adversely affect server performance when delivering
complex static files (HTML pages containing images, etc).
This setting can be increased on a host computer with sufficient RAM installed. However, since the
number of static files being served by Device Manager is only in the order of a few pages,
performance gains would most likely be quite trivial. Under normal conditions, you do not need to
change the default value of this property.
Default: 10000000 (bytes)
A-2-17 server.http.cache.maxFileSize
This property specifies the maximum size (in bytes) of a file to be stored in the Device Manager
internal cache. If a file larger than the specified size is requested, the Device Manager server reads
the data from disk without using the cache. If this property is set to 0, performance might be
degraded because the cache is not used. Under normal conditions, you do not need to change the
default value of this property.
Default: 100000 (bytes)
A-2-18 server.http.fileTypes.noLog
This property specifies the file types that are not logged in log files. If you specify multiple types,
separate them with commas. Spaces are ignored. This property prevents the access log from
overflow with entries related to files such as graphic files, JavaScripts, or cascading style sheets
(CSS). If you specify the default value for this property, only the HTML pages requested by a
browser or other clients are logged. If you specify nothing for this property, all files are logged.
Default: gif, jpg, jpeg, png, css, js
