Error description

  • After upgrade to 9.0.5.7 static content which was previously
    being served by Intelligent Management enabled web servers
    was returning 404 error codes.
    
    The ability to allow the IHS to server static content relies
    on the IHS not finding a match for the request in its
    routing data. 9.0.5.7 included APAR PH32919 which added the
    ability to carry url-patterns associated with filter-mapping
    definitions in the routing data Intelligent Management
    delivers to the web
    server. Post APAR PH32919, if web modules are present in the
    environment that do not define a context root and contain a
    filter-mapping pattern of '/*' that target becomes a catch
    all in the routing data Intelligent Management delivers to
    the web server and therefore no attempt to fall back to
    static routing
    by the web server is ever made resulting in 404s.

    ****************************************************************
    The ability for Intelligent Management enabled web servers
    (IMWS) to locally serve static content relies on the IMWS not
    finding a match for the request in its routing data so an
    attempt can be made to serve the content locally. APAR PH32919,
    included in fix packs 9.0.5.7 and 8.5.5.20, added carrying of
    url-patterns associated with filter-mapping definitions in the
    routing data used by IMWSs. If web modules are present in the
    environment that do not define a context root and contain a
    filter-mapping pattern of /*, that target becomes a catch all in
    the IMWS routing data and therefore no attempt will be made to
    serve the content locally as it would be matched in the routing
    data.
    

Problem conclusion

  • This APAR, PH35997, adds a way to disable carrying the filter-
    mapping url-patterns in the Intelligent Management enabled web
    servers routing data via cell custom property
    odc.filterUrlSupport. Setting cell custom property
    odc.filterUrlSupport with a value of false, synchronizing the
    change, and restarting the dmgr will disable carrying the filter
    mapping url-patterns in the Intelligent Management enabled web
    servers routing data; reverting the behavior introduced in
    PH32919.
    
    The fix for this APAR is currently targeted for inclusion in fix
    packs 9.0.5.8 and 8.5.5.20.  Please refer to the Recommended
