Appendix B Creating Manifest Files

Working with Manifest Files

In the following example, page freshness is scheduled to be crawled and checked every hour to a link

depth value of 2:

<crawler

start-url="index.html"

depth="2"

ttl="60"

If the content is not yet available at a particular URL, the prefetch attribute can be used to specify the

start time for acquisition at the specified URL. For example, prefetch=“2002-06-28 18:35:21” means the

content acquisition job can only start on June 28, 2002 and at the specified time.

The following example schedules a crawl of this website every hour to a link depth value of 2 to start on

November 9, 2001 at 8:45 a.m.

<crawler

start-url="index.html"

depth="2"

prefetch="2001-11-09 08:45:12"

ttl="60"

Specifying Shared Attributes

Attributes in single <item> tags can be shared or have the same attribute values. Instead of writing these

attributes individually for every <item> tag, you can extract them and place them in a higher-level tag

called <item-group>, where these attributes can be shared from this higher-level tag. You can create an

<item-group> tag at a level below the <CdnManifest> tag, and write <item> tags into it as subtags,

moving shared attributes into the <item-group> tag, as shown in the following example:

<?xml version="1.0"?>

<host name="http://www.cisco.com"

proto="http" />

</server>

<item-group

server="cisco-cco"

ttl="1440"

type="prepos" >

</item-group>

</CdnManifest>
