Filter - synch problems

Question

          Hi
          We are trying to use filter servlet2.3 to do some filtering before after it is
          send to the web container.
          The following are the issues we have.
          having implemented the filter as per the recommendation, the pages gets swapped.
          If two users use the site at the same time, one user's request becomes another's
          response.
          There is major concurrency issues with Filter servlet2.3 in Weblogic 6.1. If the
          doFilter() method in the inherited class
          Myfilter implement Filter
          doFilter()
          If the doFilter is synchronized the above does not happend which proves that it
          is definitety a concurrency issue. But doing the above chokes the server and it
          could not scale more than 7-8 users.
          The above happens even if the doFilter method in synchronized and even if we have
          multiple instances of teh same filter running. Multiple configurations in web.xml
          where a separate filter is assigned to filter each and every servlet, jsp, html
          etc
          Is this a bug in weblogic6.1. In that case which service pack fixes it. Is service
          pack 2 which is not out yet fixes it. This is really bad since this was a last
          minute find before we could go production.
          Please let us know immediately
          

Answer 1

According to the servlet spec, you cannot use URL mapping in the way you describe - it's either a path or a suffix, noth both. Perhaps you could separate the JSPs that require filtering into a particular path and map from that path (e.g. "/auth/*") to the filter.
Good Luck.
