OGC graphic does not load when opened in Vista Webstation inside StruxureWare Webstation

Issue

When opening an OGC graphic using Vista Webstation as a window inside StruxureWare Webstation, the OGC graphic shows "Loading..." with a small cross in the upper left corner, and the graphic never loads.

Environment

OGC

Cause

The authentication in the communication between the browser and Vista Webstation is based on sessions and cookies. Due to a security setting on some sites, the initial cookie can not be set in the browser, and the authentication between the OGC graphic page showed in the browser and the web server therefore fails.

If the graphic is opened in full screen (see below) or in a new window it will load, and subsequently all OGC graphics will work until the browser is restarted.

Resolution

On each PC that needs to access the OGC graphics using StruxureWare Webstation do the following:

1. Open Internet Explorer settings by clicking the gear in the upper right corner

2. Click "Privacy" and then "Sites"

3. Write the address of Vista Webstation (e.g. http://ip_address/webstation), click "Allow" and "OK"

4. Restart Internet Explorer
