DNSExpiration
DNSExpiration
Syntax
DNSExpiration life-secs
Description
You set the DNSExpiration directive to the maximum number of seconds
(life-secs) that any entry can remain in the server DNS cache.
Each entry in the server DNS cache is assigned an expiration time in seconds, to be
measured from the time the entry is created. The maximum for this expiration time is
set by the DNSExpiration directive. An entry can have a shorter expiration time if the
time-to-live value assigned to it by a DNS server is smaller than the value set by the
DNSExpiration directive.
Only one DNSExpiration directive is allowed in the configuration file.
Default
DNSExpiration 21600
which assigns six hours, measured in seconds
Example
DNSExpiration 24000
EncodingType
Syntax
EncodingType code-type extension-list
Description
Use the EncodingType directive to specify the identifier of the encoding type
(code-type) to be returned to a Web client requesting a file whose extension
matches an extension listed in extension-list. The returned encoding type
identifies to the Web client the kind of decoding the Web client must perform on the file
content before the content can be viewed by the user. This decoding is usually a form
of uncompression.
The items in extension-list are separated by blank spaces.
For example, if the server configuration file (httpd.config) contains the directive
EncodingType x-zip-compress Z
