' download_e2.asp
'
' By Herman Liu
'
' This ASP is to list the files under a designated directory ready for download. File names
' are streamlined in uniform upper and lower cases, and sorted in an ascending order. Page
' navigational buttons will avail themselves when there are more than one pages, and will be
' appropriately updated as and when the user switches between pages, e.g. either "Next" or
' "Previous" if there are only two pages, additional "First" and/or "Last" if more than two.
' During browsing, a user can select any file for download by clicking on its name.
