Described a problem with this module.

------------------------------------------------------------------------------

  This is an input module that determines the absolute URI to the base of the 
sitemap.
  It can help you to make your Cocoon application relocatable.
  The problem with this was described by Gianugo

  The code for this input module is attached to this page (see 'attachments' 
under 'more actions').
  
+ == Problems ==
+ 
+ This module does not work correctly if the sitemap-URI changes during the 
request.
+ Such a change may occur because of a sitemap-redirection or a call to 
Flowscript.
+ The cause for this problem is, that the SitemapURIModule computes the 
sitemap-base-URI by subtracting the sitemap-URI from the request-URI:
+ 
+   request-URI - sitemap-URI  =  sitemap-base-URI
+ 
+ For example, suppose that you have a sitemap mounted at "/a/b/", and the 
request-URI is "/a/b/c/d", you get
+ 
+   "/a/b/c/d" - "c/d"  =  "/a/b/"
+ 
+ If the pipeline redirects "c/d" to "e",
+ 
+   <map:match pattern="c/d">
+     <map:redirect-to uri="e"/>
+   </map:match>
+ 
+ the sitemap-URI changes to "e".
+ In this case, the base-sitemap-URI cannot be computed:
+ 
+   "/a/b/c/d" - "e" = ???
+ 
+ As far as I can see, this is not easily solved in the input module itself. 
Somehow, the base-sitemap-URI should be computed at the start of the request.
