Subject: Query string ignored in http.post?

I'm using Net::HTTP to do a POST operation, but the query string I send
with variable settings seems to be ignored.  Can anyone tell me what I
might be doing wrong?

  require "net/http"

  Net::HTTP.version_1_2
  Net::HTTP.start('www.myhost.tld', 80) {
    |http|
    response = http.post('/test/showvars.php', 'foo=bar&ok=quack')
    puts response.body()
  }

When I run this, none of the variables show up as having been set.

However, if I send these variables to the script via a POST operation by
submitting them from a web page inside of a form like the one below,
I indeed see them as having been set:

  <form action="http://www.myhost.tld/test/showvars.php" method="post">
  <input type="hidden" name="foo" value="bar">
  <input type="hidden" name="ok" value="quack">
  <input type="submit" name="Submit" value="Submit">
  </form>

Also, this has nothing to do with the /test/showvars.php script itself,
as I see the same results with any and all CGI's and servlets that I
invoke via http.post operations.

If I use the 1.1 version, I have the same problem with the POST:

  require "net/http"

  Net::HTTP.version_1_1
  Net::HTTP.start('www.myhost.tld', 80) {
    |http|
    response, body = http.post('/test/showvars.php', 'foo=bar&ok=quack')
    puts body
  }

However, when I run this as a "GET", the variables get set fine:

  require "net/http"

  Net::HTTP.start('www.myhost.tld', 80) {
    |http|
    response = http.get('/test/showvars.php?foo=bar&ok=quack')
    puts response.body()
  }

I assume that I must be doing something wrong with the http.post
operation, but I can't figure out what that might be, since what I have
done seems to follow the Net::HTTP documentation.

Any ideas?

Oh, I almost forgot this:

  % ruby --version
  ruby 1.9.0 (2004-08-03) [i386-freebsd4.0]
  % uname -sr
  FreeBSD 4.0-STABLE

... and here's the showvars.php script:

  <?php
  $result = '';
  if (isset($HTTP_POST_VARS)) {
     $result .= "HTTP_POST_VARS:\n";
     while (list($key, $val) = each($HTTP_POST_VARS)) {
        $result .= "  $key=$val\n";
     }
  }
  if (isset($HTTP_GET_VARS)) {
     $result .= "HTTP_GET_VARS:\n";
     while (list($key, $val) = each($HTTP_GET_VARS)) {
        $result .= "  $key=$val\n";
     }
  }
  ?>
  <html>
  <head>
  <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
  <META HTTP-EQUIV="Pragma" CONTENT="no-cache">
  <title>Show variables</title>
  </head>
  <body>
  <b><pre>
  <?php echo $result ?>
  </pre></b>
  </body>
  </html>


Thanks in advance.
