I'm not seeing this behaviour..
Although if you access a directory without a trailing slash on the URL -
there'll be a redirect issued by the server and therefore another hit.
Do you think maybe that's what you're seeing?
With something like:
 io:fwrite("----->rewrite_mod called for request: ~p\n",[ARG#arg.req]),

at the top of arg_rewrite  - do you see a URL hit twice but first without a
slash and then with?

This wouldn't explain why you'd get multiple printouts for a file access
such as http://xxxxx/aaa/bbb/ccc/index.html  - so maybe your issue is
different.

Anyway- this raises an issue with the dir listings that yaws_ls spits out.
The URLs it creates for directories don't have a trailing slash - so as you
click down through each folder there's an extra round trip to the server due
to the redirections. No big deal - but not efficient. I'll take a look at
modifying that.
