Well, to answer your technical Q about the RFCs. With a 204 reply the
content-length header is usually optional. Squid sends a few headers
like connection: and content-length: on a lets-be-safe basis.

The RFCs specify that the content-length:0 MUST exist for certain
request methods (OPTIONS being one, was that what you meant by "the
streetview options"?). And MUST NOT exist for certain types of encoding
replies. That is all.

content-length is OPTIONAL in all other bodiless cases.

Disclaimer: I'm not an authority on the RFCs. Just spent lots of time
reading figuring out the text.
