This is a demo of a model for pagination that differs from others. It has many features that distinguish it from other methodologies, not the least of which is multiple selection of items in the pages. Another feature is that it does not suffer the limitations of html requests lengths, since it uses sessions. Also, it does not go to the database well for each page. Typically, for a given set of access parameters, it only accesses the database once, caching away the results in a session variable. Paging is thus more fluid. It also uses HTML form submit buttons, in conjunction with a select for page jumps, to page through the document as opposed to hyperlinks. This makes for cleaner code in general.
