/** A temporary hack for servicing EDO (common infrastructure) URLs.  Until I can figure
  * out how to mount multiple Wicket pages at a single mountpoint (e), I'll instead
  * redirect from that point to the standard points for the various service pages.
  *
  * <p>Design note: EDO is no actual standard, however.  When a standard is actually
  * required, e.g. for pollwiki link targets, then it should probably be implemented using
  * a filter or servlet that is external to the Wicket filter and dedicated to the
  * standard alone.</p>
