Hi there,
We are running polymix-3 test recently.
Everything seems to be working fine, except reload request.
Polygraph 2.5.x handles reload request as inserting following
fileds into HTTP request header.
"Pragma: no-cache"
"Cache-control: no-cache"
When our cache cache encounters above header, it validates
the object and serve cached copy if valid.
So our cache serve cached copy when reload request, which yields
error report in polymix-3.
Is our approach incorrect?
HTTP 1.1 specification indicates that
* Cache-control: no-cache
-> revalidation must occur before serving object (a)
* Pragma: no-cache
-> application(cache) should forward the request to the server
even if cached object exists (b)
-> same semantic as Cache-control: no-cache when appeared at
request header (c)
Our cache approache follows (a). And due to (c), we consider (b) as
obsolete item.
