The protocols defined for client communication with QVS are listed below.
Protocol Description
QlikView Protocol (QVP) Encrypted, binary, and TCP-based; communicates directly with QVS on port 4747.
QVPX XML-based; communicates with the QVS using http/https through a web server.
Windows clients (.exe/.ocx) communicate directly with QVS using QVP on port 4747. These clients do not require a web server to establish and maintain a connection with QVS.
The AJAX client and mobile clients do not communicate directly with QVS. They establish and maintain a connection using the QVPX protocol through a web server, QlikView Web Server (QVWS) or Microsoft IIS. This is normally done using port 80 (http). The web server, in turn, communicates with QVS using the QVPX2 protocol on port 4747.
