Nah, seems a misunderstanding here.

For the *regex engine* you don't need to escape the slash at all. It's the
context, which insists on it (like in perl). The delimiter of the regex is a
slash (ehm, two slashes, one left, one right).

The problem, you've experienced is, that the httpd 1.3 parser actually doesn't
care about the right slash (it just drops it, if it exists) -- I've glanced over
the relevant code snippet in 1.3 ;-). The 2.x parser is way more consistent
(like the perl one) and looks for the next unescaped slash. Thatswhy all slashes
which are not meant as delimiters must be escaped - regardless of their meaning
for the regex engine.
