or
Resolution status:

3) Cascaded proxies.

a. Section 4.1.3

Statement to be inserted:

"Whenever the requester is another transformation proxy, the
receiving proxy MUST treat it as a non-browser agent. The
receiving proxy SHOULD rely upon the presence of alternative
X-Device- HTTP fields and the values in the via HTTP field as
per 4.1.6.1 to detect that it is placed downstream from a
chain of proxies."



b. Section 4.3.2

Statement to be inserted:

"As per section 14.46 of RFC2616, 214 Transformation applied
MUST be added by an intermediate cache or proxy if it applies
any transformation changing the content-coding (as specified
in the Content-Encoding header) or media-type (as specified in
the Content-Type header) of the response, or the entity-body
of the response, unless this Warning code already appears in
the response.

A proxy receiving a 214 code MUST NOT change it."


c. Section D.4

Eliminate entirely.

Rationale: together with 4.3.1, 4.3.2, 4.1.2, 4.1.5.5, 4.1.6.1,
4.3.6.1, these changed sections entirely solve the issue of cascading
proxies in a standards-compliant way.
