Manifest File Structure and Syntax
– The prefix attribute applies to a URL including all of its links or subdirectories. However, the
accept attribute allows the URL and its links and subdirectories to be evaluated separately.
• reject
The reject attribute is optional and uses a regular expression to reject a URL if it matches the reject
regular expression. The reject regular expression is checked after checking for a prefix URL match.
If a URL does not match the prefix, it is immediately rejected. If a URL matches the prefix and the
reject parameters, it is rejected by the particular reject constraint. (See the “Writing Common
Regular Expressions” section on page B-5 for more information on using regular expressions.)
Note the following two key differences between the reject attribute and the prefix attribute:
– The prefix attribute uses an exact string match, while the reject attribute uses a regular
expression.
– The prefix attribute applies to a URL including all of its links or subdirectories. However, the
reject attribute allows the URL and its links and subdirectories to be evaluated separately.
• max-number
The max-number attribute is optional and specifies the maximum number of crawler job objects that
can be acquired.
• maxTotalSizeInB/KB/MB
The maxTotalSizeInB/KB/MB attribute is optional and specifies the maximum total content size in
bytes, kilobytes, or megabytes that this crawler job can acquire. The size attribute can be expressed
in megabytes (MB), kilobytes (KB), or bytes (B).
This attribute replaces the max-size-in-B/KB/MB attribute, which continues to be supported for
backward compatibility only.
• srcPrefix
The srcPrefix attribute is optional and must be used in conjunction with the cdnPrefix attribute to
form a relative CDS network URL. If a srcPrefix attribute is not specified, or if the prefix of the
relative source URL does not match the srcPrefix attribute, then the relative CDS network URL is
the cdnPrefix value combined with the relative source URL. For example, if these content objects
have the same source URL prefix “acme/pubs/docs/online/Design/” and you want to replace this
prefix with a simple “online/,” then specify srcPrefix=“acme/pubs/docs/online/Design/” and
cdnPrefix=“online/.”
• cdnPrefix
The cdnPrefix attribute is optional and must be used in conjunction with the srcPrefix attribute.
• wmtRequireAuth
The wmtRequireAuth attribute is optional and determines whether users need to be authenticated before
the specified content is played. When 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 process of discovery approach is used to determine the value: 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 set to true, the Origin Server field in the 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.
