4 Handlers

By the word handler we mean a file handler, this is to say an object that allows to handle a file: inspect the data it contains, and change it.

The itools.handlers package relies on the itools Virtual File System (see Chapter 11). This means that we can handle remote files, for example we can do this:

    >>> import itools.http
    >>> from itools.html import HTMLFile
    >>> page = HTMLFile('http://example.com/')

It is also included a database system, which basically offers lazy load, caching and atomic transactions.
