Can anyone provide a list of which servers actually allow one to do
this without going so far as to wrap everything in CGI scripts?
According to the HTML 2.0 DTD:

  HTTP servers may read the content of the document <HEAD> to generate
  header fields corresponding to any elements defining a value for the
  attribute HTTP-EQUIV. 

  NOTE 
      The method by which the server extracts document meta-information
    is unspecified and not mandatory. The <META> element only provides
    an extensible mechanism for identifying and embedding document
    meta-information -- how it may be used is up to the individual
    server implementation and the HTML user agent. 

I tried using the META tag to get the server (NCSA httpd 1.4) to
include this tag and the document always shows up in the Netscape 1.12
cache.  Is NCSA httpd one of the servers that doesn't support this?
Which ones do?

Here is the HTML file contents:

<HTML>
<HEAD>
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<TITLE>Foo</TITLE>
</HEAD>
<BODY>
<H1>foo</H1>
</BODY>
</HTML>

Am I missing something here?
