Too short, insufficient information.

[edit] NAPTR rewrites

The article states:

"Several NAPTR records can be chained together creating fairly sophisticated URI rewriting rules. A record can go through any number of rewrites before reaching a terminal condition."

RFC 3403 states:

"The regular expressions MUST NOT be used in a cumulative fashion, that is, they should only be applied to the original string held by the client, never to the domain name produced by a previous NAPTR rewrite."

It is my understanding that the RFC 3403 explicitly forbids the kind of functionality that the article says is possible. I will change this soon if there are no objections.

A response:

The reference for your point should be RFC3402, section 2, which is what RFC3403 refers to. The relevant text is "An Application MUST NOT apply a Rule to the output of a previous Rule. All Rewrite Rules for all Applications must ALWAYS apply to the exact same Application Unique String that the algorithm started with."

So, to be clear, chained rewriting is allowed, but not if the output of one rule is used as the input of the next.
