Web browser which checks availability of hot links

摘要

A web browser checks availability of hot links on a displayed web page. The web browser requests header information from one or more servers for a plurality of hot links on the displayed web page. In response to receipt of the header information for one of the hot links, the web browser indicates on the displayed web page that the one hot link is available. In response to failure to receive the header information for another of the hot links, the web browser indicates on the displayed web page that the other hot link is not available.
