The problem was that /%3F corresponds to a URL which is literally '/?'

(question mark is not the separator for query variables). In this case

a "string match" operation to determine the suffix based on this

string will lead to unexpected characters since '?' is a match

character. This lead in turn to a problem with redirects to the

internally redirect of custom error pages. So, in this case (and

probably others) the custom error page was not displayed.
