<sect1>CT_File
<p>

To let Session use a file as a container, you use
CT_Fole. 

<sect2>Instance variables
<p>

<table>
<tabular ca="">
file&lowbar;path<colsep>The path of the directory where to write the files (must exist already AND must be writable by the server process)<rowsep>
</tabular>
<caption>Accessible instance variables.</caption>
</table>

<sect2>Example
<p>

Use a subclass to provide the appropriate parameters 
to your container. Usually your subclass looks like this: 

<tscreen><code>
class My&lowbar;File extends CT&lowbar;File {
	var $file&lowbar;path = "/tmp/";
}
</code></tscreen>

You can then use My&lowbar;File in class Session. Reference it
by putting "My&lowbar;File" in the "that&lowbar;class" variable.
