Hi,

Somehow you set a cache control or you have some proxy who is doing
that in between

10.3.5 ***304**** Not Modified

If the client has performed a conditional GET request and access is
allowed, but the document has not been modified, the server SHOULD
respond with this status code. The 304 response MUST NOT contain a
message-body, and thus is always terminated by the first empty line
after the header fields.

The response MUST include the following header fields:

      - Date, unless its omission is required by section 14.18.1

If a clockless origin server obeys these rules, and proxies and
clients add their own Date to any response received without one (as
already specified by [RFC 2068], section 14.19), caches will operate
correctly.

      - ETag and/or Content-Location, if the header would have been
sent
        in a 200 response to the same request

      - Expires, Cache-Control, and/or Vary, if the field-value might
        differ from that sent in any previous response for the same
        variant

If the conditional GET used a strong cache validator (see section
13.3.3), the response SHOULD NOT include other entity-headers.
Otherwise (i.e., the conditional GET used a weak validator), the
response MUST NOT include other entity-headers; this prevents
inconsistencies between cached entity-bodies and updated headers.

If a 304 response indicates an entity not currently cached, then the
cache MUST disregard the response and repeat the request without the
conditional.

If a cache uses a received 304 response to update a cache entry, the
cache MUST update the entry to reflect any new field values given in
the response.
