XCH_PROB is a field of the XCH_PREFETCH tag which indicates the probability of the specified URL being selected.

Examples

This tag tells the client that there is a 50 percent chance that the specified URL will be accessed next. HTML clients could provide users with a 'Preferences' page which allows the user to specify a minimum probability for pages to prefetch.

<xch_prefetch href="http://www.chaco.com/" xch_prob=0.5>

This set of tags indicates that about half of the time, users go to 'doc1.html' next, about 30 percent of the time, they go to 'doc2.html', and 20 percent of the time, they go to 'doc3.html'.

<xch_prefetch href="http://www.chaco.com/doc1.html" xch_prob=0.5>

<xch_prefetch href="http://www.chaco.com/doc2.html" xch_prob=0.3>

<xch_prefetch href="http://www.chaco.com/doc3.html" xch_prob=0.2>
