It kind of works. I made the change to %1 and when I made a request ...

/test.php?pdfId=12

.. then it gave me the pdf. SWEET. But, still dies after the first
mapping. If I call that same exact URL  again, i get redirected to ...

/pdf/

.. with no filename. Odd. I added these directives....

RewriteLog "/var/log/httpd/rewrite_log"
RewriteLock "/var/lock/httpd/rewrite.lock"
RewriteLogLevel 2

.. but nothing ever is written to /var/log/httpd/rewrite_log, and
/var/lock/httpd/rewrite.lock never shows up. I put those directives in
the main server config, not the virtual host that I'm talking about.
My apache is running as user 'nobody' and the permissions on those
files/dirs are ..

/var/lock/:
drwx------  2 nobody root 48 Aug 12 11:35 httpd

/var/lock/httpd/:
total 0

/var/log/:
drwxr-xr-x  3 nobody  nogroup     168 Aug 12 11:37 httpd

/var/log/httpd/:
-rwx------  1 nobody root   0 Aug 12 11:36 rewrite_log
