Objective:
I want to dynamically update the content with strings and JPEG images received from a TCP/IP socket. For this purpose, I am exploring the possibility of utilizing the Web Browser feature of the Visualization toolbox.

Example:
In a standard web browser, entering data:text/plain;charset=utf-8;base64,SGVsbG8gc3RyYW5nZXI= in the URL window will display "Hello stranger" on the webpage.

Issue:
When attempting to use this method in the Web Browser of the Visualization toolbox, the content does not display as expected. Instead, it shows the error:'Navigation to the webpage was canceled.'.

Request:
I seek guidance on how to resolve this issue so that the Web Browser in the Visualization toolbox correctly interprets and displays the data URI content.

Alternative Solution Welcomed:
Or, if it is possible to directly use Codesys Structured Text (ST) variables within an HTML page, this approach would also meet my requirements.

Thank you for your attention.
