RE: [cgmo-webcgm] MIME Media Type for ECMAScript

[Robert Orosz <roboro@auto-trol.com>]

Lofton,

I've attached the screenshot (Error.JPG) and the HTML page
(mediaTypeTest.html).  Hopefully, they will come through.

I forgot about the screenshot in my original message, but I *did* attach the
HTML page.  It was also attached to the message that I got back from the
list.  However, I see that you did not get the attachment, and OASIS
archived copy [1] doesn't seem to have the attachment either.  This is very
strange.

Rob -- thanks for the excellent summary.  Could you please also send to the 
list:  your test program; the screenshot of the MessageBox you get?

All -- if you have anything to add (or challenge), please do so by ReplyAll.

Thanks,
-Lofton.

Title: ECMAScript media type test

ECMAScript media type test

This page tests to see if your browser can run ECMAScript scripts when the type attribute of the script element is "application/ecmascript" instead of "text/ecmascript" (IANA deprecated the latter media type). The test is executed immediately when you open this page, and the results are shown below.

Oops!

Your browser did not correctly execute this test. Additional error messages may appear in a popup window.
