WWWOFFLE Cache Indexes

The index of all of the pages stored in the WWWOFFLE cache is available in a number of formats.
The indexes are organised by hostname with a separate list for each host. The basic URL is /index/, but this can be modified with a path as follows.

/index/: The main index that has links to all of the other indexes.
/index/http/: A list of the http pages that are cached (or any other protocol).
/index/http/www.gedanken.demon.co.uk/: A list of the http pages that are cached from the host www.gedanken.demon.co.uk (or any other protocol and host).
/index/outgoing/: The list of requests waiting to be fetched.
/index/monitor/: The list of requests for pages that are monitored on a regular basis.
/index/lasttime/: The list of pages that were accessed the last time that the program was online. This also provides access to a history of the pages accessed the previous three times online.
/index/latest/: An index of all files modified in the last few days.

WWWOFFLE Single and Recursive Page Requests

Pages that are wanted can be fetched by entering them into the browser's own page selector. Or alternatively by using the command line interface or interactively from a WWWOFFLE web page form.

/refresh-options/: An interactive page for specifying the fetching pages recursively.

WWWOFFLE Monitor Page Requests

Pages that are wanted on a regular basis can be fetched by entering them into a WWWOFFLE web page form.
