Tài liệu Integrating ColdFusion MX with Other Technologies

In this chapter, we introduce some features in ColdFusion that you
may consider using to enhance your application. They’re not new
to ColdFusion MX, but they’re certainly classics, and they’re often
misunderstood (or plain missed) by many CF developers.
Each may involve some coordination with the CF Administrator, but
we cover what you need to know so that you can effectively address
any considerations that they may raise.
The first, CFSCHEDULE, enables you to create automation processes
that execute at scheduled intervals. This can prove very useful if you
have some process that needs to run repeatedly or at some point in
the future. We discuss both setting up and using the scheduling
features.
The second, CFFILE, is one of the richest of all CF tags in that it can
perform many different functions, which can be broken into three
broad areas. As suggested by its name, it enables the manipulation of
files on the CF server. In one respect, it enables the processing of files
as a whole (moving them, deleting them, and so on). In another
respect, it enables you to read from and write to files. Finally, it also
enables you to upload files from the client via a special HTTP form
feature. We discuss each of these.
The third feature, Verity Indexing, enables you to create a searchable
library of files on your server, which can be especially useful if you
have a large number of HTML documents, word-processing files,
spreadsheets, presentations, and Acrobat PDF files, to name just a
few. The process of creating, populating, and searching an index of
such files is quite straightforward and may be one of the underutilized
features in CF. We show you the basics and point you to other
resources to learn still more, including how to leverage the Verity
index capability to add more power to database searching as well
