Using a custom proxy
                When creating a custom proxy, the following conditions must be fulfilled:
- Cookies are copied from the client request to the server request.
 - Headers are copied from the server response to the client response.
 - The server response is copied in binary form to the client response.
 - The QvAjaxZfcPath property is retrieved from the Web.config file.
 - 
                        
The requested file is sent using querystring using 'file='.
 
Example:
url=/QvWebSite2/Proxy.aspx?file=QvsViewClient.aspx&mark=&host=Local&view=Films&platform=WORKBENCH&dpi=96
                The QvAjaxZfcPath, http://<SERVERNAME>/QvAjaxZfc/, is retrieved from the Web.config file. The proxy performs the following request:
http://<SERVERNAME>/QvAjaxZfc/QvsViewClient.aspx?mark=&host=Local&view=Films&platform=WORKBENCH&dpi=96
