<em>CondPattern</em>, back-references are internally created
which can be used with the strings <code>$N</code> and
<code>%N</code> (see below). These are available for creating
- the strings <em>Substitution</em> and <em>TestString</em> as
- outlined in the following chapters. Figure 1 shows to which

locations the back-references are transferred for expansion as
well as illustrating the flow of the RewriteRule, RewriteCond
matching. In the next chapters, we will be exploring how to use
