Research direction

Start by reading the aggregator2 module's existing caching logic and the code that serves aggregated metadata over HTTP. Trace how response headers are currently produced, then verify that conditional requests using Last-Modified/If-Modified-Since and ETag/If-None-Match can return the appropriate not-modified response. Done means clients can efficiently poll without receiving unchanged metadata.

Description

enhancement help wanted

From vis...@terena.org on February 08, 2012 23:23:03

Add support for conditional HTTP GET requests in the aggregator module. This would enable clients to efficiently poll for aggregated metadata.
Could be implemented using Last-Modified/If-Modified-Since and ETag/If-None-Match headers.
The aggregator2 module seems to already have some caching logic onboard, so it makes sense to implement it there.
