See below for answers to your questions. I'm beginning to wonder at this
point if I should abandon this approach and try -prog. The only problem is I
was having fun trying to figure out a configuration file to crawl my site. I
thought it was using filters too and would have the same problem.

188.8.131.52/affidavit.pdf should get you to the pdf in question. There is
another pdf named terminationchecklist.pdf in the directory too which causes
the same problems. I do have a firewall running on my pc so if you have
problems let me know your ip and I'll allow it in.

When I run swish-e -h I'm getting version 2.2.3 and have been running with
the DEBUG_FILTER set to 1. I just downloaded the latest version about 3
weeks ago and assumed I had the latest. I used the swish-e-2.2.3-win32exe
link to download the version I have.

My Swishspider does contain the lines below. Here are the top lines from my
print STDERR "spider $$ [@ARGV]\n";

I ran swishspider this way and the contents file contained the page with the
malformed meta tags and the response file contained the text/html line. The
only thing I could see wrong with the files is the meta tags.
