You can mount more than one access point on one QV server.Please go to the QEMC--->Set Up--->QlikView server----->Folders------->Here you can select your access point folder by going "My network places".
thanks for your suggestion. i tried it , and works! but how could i build two websites for each accesspoint. for example, one accesspoint with website is http://servername and another is http://servername:8080?
