I'm working on a CGI script that creates a dynamically generated .js
file. What MIME type should I use? Every site I go to says something
different: text/javascript, application/javascript,
application/x-javascript, or application/ecmascript. Which one is it?

The Content-Type header isn't usually as important as the type
attribute, however the two should match.
The application/ecmascript and application/javascript MIME types were
only recently introduced, so this means that most (all?) user agents
will not recognise them for the time being. As such, you should continue
to use the (officially obsolete) text/javascript type.

Mozilla and Opera recognise application/javascript. I think IE is the
only major browser that doesn't, but I'm not certain about Mac and Linux
browsers. I don't know about application/ecmascript support.

Yes, even though text/javascript is now deprecated, it's the only one
that can be safely used in HTML while IE6 is still around. However,
IIRC, IE obeys the type attribute regardless of what the server sends.
Although, it is generally good practice to use the same MIME type in
both places anyway, you can use:
<script type="text/javascript"></script>
and send this in the HTTP headers:
Content-Type: application/javascript; charset=UTF-8
(don't forget to send the correct character encoding information, it
must match the encoding of the file)

Only in the default configuration on XP SP2, although I'm not
completely sure which of many settings actually stops it
unfortunately.

IIRC, text/javascript was never a registered mime type to begin with,
was it?

I assume you mean within the Content-Type header? Use with the type
attribute will result in the user agent ignoring the script.
"Recognise" would seem to be an overstatement. If they recognised the
MIME type, it would be usable within the type attribute. Tolerate would
be more accurate, I think.

Yeah, sorry. I knew they accepted it in the Content-Type header and
Deer Park Alpha 2 accepted it in the type attribute, although it seems
that older versions of Mozilla (including Firefox 1.0.x) don't. I also
incorrectly assumed Opera 8.0 supported it in the type attribute.

Maybe the script should recognize the browser and send
"text/javascript" or "applicatio n/javascript" depending on which
browser they have?

browsers don't advertise their acceptance of javascript mime-types.
Just use text/javascript, it's deprecation is not important until
browsers support others.

I'm writing a web application that fetches documents from the server and
sends them to the client. I do this using the Response.BinaryWrite method.
However, is there any way to detect the MIME type of a given file? Or a
catch-all MIME type I could use? These files will likely mainly be word and
pdf documents, but they can conceivably be anything.

It is not possible with client-side JavaScript. Some browsers

Hi there,
So here is the situation I'm in. My PHP script does something like
this:
1. Update a DB (only once)
2. Send some post data to another PHP script (only once)
3. Output some stuff related to 1 and 2.
I've done #2 by using input type="hidden" on a form, like so:
print "<form action='../dir/register.php' method='post'

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
