Says ichimunki:
Since you're being incredibly helpful, can I impose on you further than anon_monk did?
Um, no. Now you're asking me to read you the manual.
If you read it and you don't understand,
then I will try to answer. You could also try writing
a few small example programs to test out your guesses
about how it works.
is there a way to insert a last/return clause into the callback which
aborts the request?
The general pattern for such things in Perl is:
eval { $ua->request($request, \&callback, 4096) };
if ($@ =~ /^Request aborted/) {
# handle aborted request
} elsif ($@) {
die;
}
sub callback {
# ...
die "Request aborted" if ...;
# ...
}

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).
