Re: generating a 404 response in an xsp based pipeline

One way to solve the problem would be to throw a domain-specific exception in the generator and use a selector for this exception in the map:handle-errors for the pipeline. For example:

<map:handle-errors>
   <map:select type="exception">
     <map:when test="our-custom-exception">
       <map:generate src="niceerror.xsp" type="serverpages"/>
       <map:transform src="html/site2html.xsl">
         <map:parameter name="pageTitle" value=": Resource not found"/>
       </map:transform>
       <map:serialize status-code="404"/>
   </map:when>
</map:select>
</map:handle-errors>

Hello,

Does anyone now how to generate a 404 error page in xsp? We have an xsp-page searching a database for hits on clicked hyperlinks. Because the site is also visited by search engines, I want the server to respond with 404 status page as soon as the query returns no result. Otherwise the webcrawler would spider several 'sorry no result found' - pages. That would not make any sense at all.

What I have been trying so far is to use the action logicsheet to redirect to an unknown uri to let cocoon serve the error page. But the use of the action logicsheet is not allowed within a generator.

Does anyone have hints on how to solve the problem?? Best regards Thorsten
