web_page_module where served using a different cache. This was due to the fact
that web_page.getPath() was used as key to find the corresponding cache (and
the path of a web page is not the same through web_page_module and through a
web_site). Now, orginal_path is stored on web_section and used
instead of path. This permit to served cached web_page throught web_page_module
or throught a web_site.
