Subject problem with log url overflow found
Date Sat, 11 Jan 1997 20:34:07 GMT
Check out http_request.c, line 160:

        rv = stat(path, &r->finfo);

On some systems, when you get too many '/'s, the stat will return -1.
That is why some people can't see it.  I would be other web servers 
(and lots of other programs) have the same problem.

I added some debugging output and got the below on a FreeBSD 2.1.5
system.  Note the line that says "stat of /usr/local... returned
-1".  A log from a trial with less '/'s is shown below this log.

Trying "http://alive/////////////////////////" gives what is expected:
