hello, how are you?
I have a question,
I'm using D2R and I query data by the Virtuoso sparql endpoint.
I'm having problems with the Virtuoso directives:
get:soft "replacing"
get:refresh "5"
the first one indicates that data must be got from the source and not from
cache,
and the second one indicates the time in seconds that will keep data in
cache, after that time it reloads data.
To know that that time has past Virtuoso reads HTTP headers and uses the
"Date", "ETag", "Expires", "Last-Modified",
"Cache-Control" and "Pragma: no-cache" fields to calculate when the resource
should be reloaded.
The problem I'm having is that data is always got from cache, and I think
this happens because one or more of these tags are missing
in the http header of D2R response.
So, what I would like to ask you is if there is a way to force that the
response given by D2R includes these properties in the header,
so that updated data can be got after the specified time has past.
Thank you very much.
Regards,
Juliana Quiñones
