Hi Dariusz, Thanks for the input. After some coding and reading in the Struts 2.0.2 sourcecode I got this to work.
In general it seems that Struts2 uses two methods from the request to examine URI (in this order): - request.getServletPath() - request.getRequestURI() The real trick is, as you suggested, to create my own instance of HttpServletRequest and implement set-methods for those two, manipulate the values and pass on the reference to filter.doFilter(req, res). The nice thing is that there is a javax.servlet.http.HttpServletRequestWrapper class that do a base implementation of the request. Extend that and implement setServletPath(String arg0) and setRequestURI(String arg0) methods. Very nice! ------ Martin Gainty- Thanks for your input to my question. As you understand of my answer above, a redirect from an JSP page is way to late in the request sequence. The thing with keywords is to implement Wiki functionallity into a normal Struts built website. If a client request http://somesite.com/keyword my filter ask the WikiEngine if it recognizes the keyword. If it does, I modify the request to my template.action instead. I store the Wiki keyword as an request attribute to be picked up and presented by the template. By this I can serve simple easy editable pages in Wiki format and use Struts for more advanced pages. An important goal is to hide the redirect for a web browser so when a user bookmarks a page, the url point to a keyword and not an ugly redirect. ------ Thanks again for the help!
