// with plenty of reusable code in case anything similar (not necessarily PDF files, not necessarily this exact WT function, etc.) is ever needed again.

// 15Feb2007 -- modified so it returns only the *relative* path (i.e. "http://agapps16.agric.gov.ab.ca/$dept/dbfile.nsf/view/dockey/file.pdf?OpenElement&parm1=value1#anchorX" returns "$dept/dbfile.nsf/view/dockey/file.pdf")

// 18Jul2007 -- no longer a "Page", now a "Javascript Script Library" to prevent IBM WebSEAL's annoying problem with inserting the SCRIPT tag doc.cookie=... into HTML pages >:(
