RE: mod_rewrite to fix trailing slash problem

Well, the problem is that this applies to thousands of URLs.  Generally,
Apache does the redirection for you, but I've read somewhere that sometimes
Apache's redirection can be  broken by other mod_rewrite rules.  I've
inherited this system, and the config files are thousands of lines long, so
I haven't had time to analyze all the scenarios yet.  But I do know that
this wasn't a problem on Apache 1.3, and when I upgraded the system to
Apache 2.2, links to folders without trailing slashes broke.  :\

It's a bad idea to rewrite in this case, since it can cause all kinds of 
problems with relative URLs.

Better to redirect:

Redirect permanent /blah http://www.foo.com/blah/
