Appendix B Creating Manifest Files
Working with Manifest Files
Specifying Time Values in the Manifest File
The following attributes require that you enter a time value in the format yyyy-mm-dd hh:mm:ss
(year-month-day hour:minute:second):
• prefetch
• serveStartTime
• serveStopTime
• expires
• time-before
• time-after
In the Manifest file, the time string conforms to the yyyy-mm-dd hh:mm:ss format. A time zone
designation can be specified optionally at the end of a time string to indicate the particular time zone
used. If a time zone designation is omitted, the GMT time zone is used. Note that automatic conversion
between daylight saving time and standard time within a time zone is not supported, but a special
designation for daylight saving time can be used, such as PDT for Pacific daylight saving time. In the
following example, the prefetch time is September 5, 2002 at 09:09:09 Pacific daylight saving time:
<options timeZone="PDT" />
ignoreQueryString Playback attribute that can be used with the <options>, <item-group>, <item>,
and <crawler> tags. If ignoreQueryString is set to true, then the CDS software
ignores any string after a question mark (?) in the request URL for playback.
If this attribute is omitted, then the default value is false.
For example, content with the request URL url=http://web-server/foo has been
prefetched. If a user requests content with the URL
url=http://web-server/foo?id=xxx and the ignoreQueryString attribute is set to
false, then the CDS software will not use prefetched content from the request
URL http://web-server/foo.
However, if the ignoreQueryString attribute is set to true, then the CDS
software treats the request URL http://www-server/foo?id=xxx the same as
http://www-server/foo and returns prefetched content.
wmtRequireAuth (Optional) Determines whether users need to be authenticated before the
specified content is played. When wmtRequireAuth is set to true, the Service
Engine requires authentication to play back the specified content to users and
communicates with the origin server to check credentials. If the requests pass the
credential check, the content is played back from the Service Engine. If this
attribute is omitted, a heuristic approach is used to determine the setting: if the
specified content is acquired by using a username and password, wmtRequireAuth
is set to true; otherwise, it is set to false. For FTP, if the username is anonymous,
wmtRequireAuth is set to false.
Note If wmtRequireAuth is true, the Origin Server field in the CDSM
Content Origin page for this delivery service needs to point to the
server that can authenticate the users. When users want to play back
the content, the server specified in the Origin Server field is checked
for authentication.
