Maybe I am just lucky and my application works with current library (5.0a) and breaks with the next version, or perhaps the following piece of code (copied from some examples) helps me? HTRequest_setReloadMode(obj->request, HT_CACHE_FLUSH); if (!HTLoadAnchor((HTAnchor *)obj->anchor, obj->request)) ... ... Hopefully, that CACHE_FLUSH disables the check for anchor document in memory cache filter when I really want to start a new load operation. -- Markku Savela (msa@hemuli.tte.vtt.fi), Technical Research Centre of Finland Multimedia Systems, P.O.Box 1203,FIN-02044 VTT,http://www.vtt.fi/tte/staff/msa/
