print header('application/pdf'), do {
open my $fh, '<:raw', 'minimal.pdf' or die "D'Oh! $!\n";
local $\;
<$fh>;
};
Due to the funny way CGI::header() operates under mod_perl it is advisable to always print the result of CGI::header immediately and never defer it. In this particular case it probably doesn't matter but one day it may.
print header('application/pdf');
{
open my $fh, '<:raw', 'minimal.pdf' or die "D'Oh! $!\n";
local $\;
print <$fh>;
};
Note: the above code slurps the whole PDF into memory. I prefer to use File::Copy
use File::Copy 'copy';
print header('application/pdf');
copy 'minimal.pdf', \*STDOUT or die "D'Oh! $!\n";

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).
