MSVC & Internet

Environment: MSVC 4.2b, Wnidows NT 3.51 SP5

I use MFC's collection of Internet classes to download a HTML file.
Since I haven't found a good way of parsing HTML text myself,
I use Microsoft's ICP HTML control. It's OnDoRequestEnbedded 
Event is called for embedded images. The HTML control currently supports only
HTML 2.0. The control freezes when it downloads certain pages, one
of which is the Microsoft home page. I don't know why it freezes,
but I rather not feed it a HTML document which is a version greater than 2.0.
The control won't get files using "file://".
I use CHttpFile::QueryInfo to obtain information on pages, but there is no 
discernible
difference between pages it reads perfectly(www.universal.com), and pages it 
chokes on (www.microsoft.com).
How can I determine the HTML level using MFC?
Why is the OCX choking on Microsoft's home page?

You can't reliably do so.  HTTP nor HTML provide for no standard
in this area, so MFC (and WININET, and any other software) are
helpless.

Some HTML documents are decorated with a DOCTYPE tag, which you
can read about in the HTML specification at http://www.w3.org. 
Nothing guarantees, of course, that the information in the DOCTYPE
tag is valid, correct, or consistent.  And, certainly, only a small
percentage of documents on the web have a DOCTYPE tag.

I'm afraid I've become some sort of speed freak.
These words are my own. I do not speak on behalf of Microsoft.
