Sure. When the user submits the request form, don't invoke the
request right away. Instead, send back something like this.
(Disclaimer - sloppy html coding below. This isn't guaranteed to be
correct, it's just intended to give the basic idea). General gist -
send back a page with the "waiting" animation that will "submit itself".
<html>
<body onLoad="javascript:document.myform.submit()">
<img src="animated.gif">
<form name="myform" method="GET" action="search.cgi">
<input type="hidden" name="query" value="what user entered">
</form>
</body>
</html>
Alternative two: send back a page that uses a refresh to execute the
actual query:
<html>
<head>
<meta http-equiv="Refresh"
content="0; url=http://yourhost.net/dosearch.cgi?query=what+the+user+said";>
</head>
<body>
<img src="animated.gif">
</body>
</html>
hth.
