René K updated USERGRID-372:
----------------------------
Description:
I want to make sure that I don't override changes by accident, so I want to use
the [{{If-Unmodified-Since}} HTTP
header|http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.28].
I expect that the server will give me a 412 (Precondition Failed) error when
the data where changed in the meantime. However nothings happens and the data
will been always overridden. There is no way to detect changes, even a check
before writing could cause a data loss. That should been fixed IMHO.
Also the [{{If-Modified-Since}} HTTP
header|http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.25] would
be great to have, I know that I can do that with the CQL too, but a 304
response is faster to detect than a empty result body.
