At least you didn't crash IE!

You seem to be interpolating @page into that gigantic here-doc. Not
that there's anything exactly wrong with that, except that you never
seem to have used @page anywhere else in your program. (Did you leave
out a big piece of your program?)
If you really do want to interpolate just one thing into a giant
document, though, there's always the risk that a hidden $ or @ in the
giant document will go un-backslashed and cause some mischief. And I
like to keep the semicolon reasonably close to the rest of the line
when I can. So I might do something like this:
my @page = &supply_web_page();
my $giant_string = <<'_END_OF_GIANT_STRING_';
blah blah blah
single quotes don't mind $ or @
MAGIC_TOKEN
Or even "quotes"
blah blah blah
_END_OF_GIANT_STRING_
# Now, interpolate and output
$giant_string =~ s/MAGIC_TOKEN/@page/;
print $giant_string;
I recommend that you add "use strict" and "use warnings" to the top of
your program, and use the CGI module's debugging abilities to debug it
from the command line before you turn it loose on your webserver. If
you get any unexplained complaints from perl, see how the perldiag
manpage says to fix those problems.
Good luck with it!
