+<faq>
+ <question>
+ How can I dynamically specify the source for my generator?
+ </question>
+ <answer>
+ <p>For example, I want the <generate>'s src attribute to be defined based on a request.
+ </p>
+ <p>
+Here are two solutions (depending on your version of Cocoon):
+ </p>
+ <p>
+(1) RequestParamAction (2.0.x + 2.1)
+ </p>
+<source><![CDATA[
+ <map:match pattern="tba/*">
+ <map:act type="request">
+ <map:parameter name="parameters" value="true"/>
+ <map:generate src="{page}"/>
+ <map:transform src="docs/samples/tba/redirect.xsl"/>
+ <map:serialize type="html"/>
+ </map:act>
+ <!-- else ? -->
+ </map:match>
+]]></source>
+ <p>
+Adding <map:act type="request"> and
+<map:parameter name="parameters" value="true"/> makes it
+possible to get the page request attribute.
+Then, you can define the src attribute by using the value of the page attribute
+like this: <map:generate src="{page}"/>.
+ </p>
+
+ <p>
+(2) InputModules (2.1)
+ </p>
+
+<source><![CDATA[
+ <map:match pattern="tba/*">
+ <map:generate src="{request:page}"/>
+ <map:transform src="docs/samples/tba/redirect.xsl"/>
+ <map:serialize type="html"/>
+ </map:match>
+]]></source>
+
+ <p>
+In addition, you may want to use ResourceExistsAction to check whether
+the provided page exists.
+ </p>
