"""Middleware that removes additional meaningless backslashes. | |
This transforms URLs as follows: | |
- yourwebsite.com// to yourwebsite.com | |
- yourwebsite.com/section/// to yourwebsite.com/section | |
Ideally, this middleware should be placed before Commonmiddleware to avoid | |
conflicts with APPEND_SLASH. However, this code already appends final slash | |
if APPEND_SLASH is set to TRUE trying to reduce one additional redirect. | |
