You really should look into Templating Solutions. Here are two for your amusement:

#!/usr/bin/perl -T

use strict;
use warnings;
use CGI;
use LWP::Simple;
use Template;

my $cgi = CGI->new;
print $cgi->header;

my $source;
if ($cgi->param('fetch')) {
   $source = LWP::Simple::get($cgi->param('url'));
}

my $template = Template->new({
   INCLUDE_PATH => '/usr/local/tt2/templates'
});
$template->process(\*DATA, {cgi => $cgi, source => $source});

__DATA__
[% WRAPPER html/page html.head.title = 'view source' %]

<form method="POST">
Enter URL: [% cgi.textfield('url') %]
<p>[% cgi.submit('fetch') %]</p>
</form>

[% IF source %]
<hr/>
<pre>[% FILTER html %][% source %][% END %]</pre>
<hr/>
[% END %]

[% END %]

HTML::Template:

#!/usr/bin/perl -T

use strict;
use warnings;
use CGI;
use LWP::Simple;
use HTML::Template;

my $cgi = CGI->new;
my $template = HTML::Template->new(
   filehandle => \*DATA,
   associate  => $cgi,
);

if ($cgi->param('fetch')) {
   $template->param(source => LWP::Simple::get($cgi->param('url')));
}

print $cgi->header, $template->output;

__DATA__
<html>
<head>
<title>view source</title>
</head>
<body>
<form method="POST">
Enter URL: <input type="text" name="url"/>
<p><input type="submit" name="fetch" value="fetch"/></p>
</form>

<tmpl_if source>
<hr/>
<pre><tmpl_var name="source" escape="HTML"></pre>
<hr/>
</tmpl_if>

</body>
</html>

Feel free to ask questions about these modules, they are designed to make your life easier - but you don't appreciate that up front. ;)

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
