Hello, I'm trying to get the "read while writer" feature working but am seeing some behavior I was not expecting or perhaps I just don't understand how its supposed to work. I saw a couple other threads regarding this but didn't see any clear resolution or open bugs for this in JIRA.
I configured ATS to use the following settings… CONFIG proxy.config.cache.max_doc_size INT 0 CONFIG proxy.config.cache.enable_read_while_writer INT 1 CONFIG proxy.config.http.background_fill_completed_threshold FLOAT 0 According to this link I found… http://www.ogre.com/node/386 To test this, I issued a request to a URI that I configured to wait 5 seconds before responding. During the 5 seconds, I issued a second request to the same URI. In my wireshark capture, I observed the first request going to the origin server and the second is blocked until the 1st request's response is returned, but rather than reading the response from cache, the second request then is made to the origin server. My expectations (or maybe misunderstanding) was that the 2nd request would read the response from cache once the 1st request's response is returned. At this point re-issuing the request returns a cached response, so I know the response is cacheable. Any thoughts? Has anyone had luck getting this feature to work?
