usually, the URL rewrite in jsp like:
<response.encodeURL("mypath/myfile.jsp")>
This will append a session id at the end of URL. if the cookie is disabled ,all of URL in the web application need to be like this.

however, in Struts, URLs are not be wrote in JSP explictly,instead, int the form:
<html:form action="myaction">

the JSPs and servlets are defined in the struts_config.xml like:
<forward name=”default” path=”/FormBasics.jsp”/>
or global forword
<global-forwards>
<forward name=”home” path=”/home.jsp” />
</global-forwards>

so, How can I use URL rewrite in struts?
