Try to remove the /htdocs part from the link, as Apache webserver assumes the content of /htdocs as it's top level directory, I may be wrong but yet it could do the job ;) Another thing, check if the *.swf file has the +r flag set. I also assume that you have put the output html from your perl script into the htdocs, and you are calling it from a web browser via http://localhost/filename.html Hope that you can pull out something usefull from this reply.
