One way to handle this is to use an HTML redirect. This has the added benefit of freeing memory in use by mod_perl processes that would otherwise be used for each waiting client connection.
An outline of how I've planned to handle it (note: I haven't implemented it yet, but plan to soon):
receive request;
if (request has no job_id) {
create new job_id;
start processing external commands (providing job_id);
return an HTTP redirect with a 10 second pause, such as:
<meta http-equiv="REFRESH" content="10;URL=http://sample.com/?id=j
+ob_id">
} else {
if (external commands have completed) {
return results;
} else {
return the HTTP redirect again;
}
}

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).
