I _just_ implemented a similar functionality to an AJAX based website for log viewing. I send the data to the client then do sorting (no filtering yet, but the OP has me inspired :) ) based on the data stored in local browser memory, rather than having to re-query the servers each time. Not very perlish, but here's what I did in case anyone is interested.
var logs = new Array();function ListLogs(response) { theDoc.getElem
+entById('logResults').deleteTFoot();
for (var i=0;i<response.getElementsByTagName('log').length;i++) {
var members = response.getElementsByTagName('log')[i];
var columns = new Array('time','passfail','protocol','status',
+'bytes','url');
var values = new Array();
for (var j=0;j<members.childNodes.length;j++) {
var node = members.childNodes[j];
for (var k=0;k<columns.length;k++) { if (no
+de.nodeName == columns[k] && node.firstChild) {
values[columns[k]] = node.firstChild.nodeValue;
}
}
}
logs.push(values);
addLog(values);
} resort('url');
}
var sortColumn = 'time';
function mysort(a,b) {
if (a[sortColumn] > b[sortColumn]) return 1;
if (a[sortColumn] < b[sortColumn]) return -1;
if (a[sortColumn] == b[sortColumn]) return 0;
}
function resort(byfield) { theDoc.getElementById('logResults').dele
+teTFoot();
sortColumn = byfield;
var tmp = logs.sort(mysort);
for (var i=0;i<logs.length;i++) {
var a = logs[i];
addLog(a);
}
}
The function addLog(rec) simply adds a row to the table of log entries.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
