Does the page load an ActiveX control unit page?

Question

I have an ActiveX control on the page that I am creating (believe me, I'm sorry I didn’t) using a static tag <object/>in the page source (it is generated by the ASPx backend, but it comes the browser as part of the raw page layout).

Does Internet Explorer start parsing and rendering to load ActiveX controls as soon as it parses the tag <object/>or loads in a parallel stream?

Answer 1

ActiveX must be loaded into the user interface thread, otherwise most ActiveX will not work because they are STAs. The same applies to IE scripting objects, some of them simply do not have a proxy server for multi-billionth sorting, so the DOM manufactory should also be in the user interface stream.

Page parsing can happen in the background thread .
