B4J Question [WebApp] Websocket and MIME-Type

Hello,

i noticed, that my Chrome-Console reported this one:

Resource interpreted as Stylesheet but transferred with MIME type text/plain: "http://localhost:51234/libraries/w2ui/w2ui-1.3.2.min.css". index.html:12

Resource interpreted as Script but transferred with MIME type text/plain: "http://localhost:51234/b4j_ws.js". index.html:16

Resource interpreted as Script but transferred with MIME type text/plain: "http://localhost:51234/libraries/w2ui/w2ui-1.3.2.min.js". index.html:13

I have ignored this, because in Chrome (and Firefox) everything seems to be correct.

But Internet Explorer V11 refuses loading the CSS-File because of MIME-Typeconflict (SEC7113). Therefore the page is not displayed correctly

Is there a way to set the MIME-Type?

Thanks in advance & Greetings ... Peter
