The issue https://github.com/das-developers/das2java/issues/170 is actually an Autoplot issue, I think.

    QDataSetStreamHandler property loads the cache tag sent.

    I think the problem is caused by the undocumented "resolution" variable in the Das2ServerDataSource. Is it an input or an output?

    I suspect changes here broken things:

    The problem was the code was expecting the cache tag to be within DEPEND_0, but the Das2Stream parser was attaching it to the data itself.

    (Potentially off topic)
    According to the 2.2.2 ICD, the properties are xCacheRange and xCacheResolution, have you seen any readers using some other property names? Just in case you do I'd prefer to fix any readers that don't follow the ICD instead of putting the burden on client programs to guess the property names.
