If you just want to verify that the file is there, try a HEAD request instead of a GET request. If that gives you a false negative (it might, depending on the server), then set the max_size attribute of your LWP::UserAgent object to something like 512 bytes, so LWP will abort very quickly:
my $ua = LWP::UserAgent->new (max_size => 512); # note extra param
my $tmpfile;
foreach my $rev ("-", ('A'..'Z')) {
$tmpfile = "$file$rev.$ext";
my $response = $ua->get("$path/$tmpfile"); # simpler interface
## you need to save $tmpfile here!
last if $response->is_success; # better than yours
}

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).

or How to display code and escape characters
are good places to start.
