Ticket #8 (closed defect: fixed)
weird issue with round-robin proxies
|Reported by:||duncan@…||Owned by:||somebody|
We had this issue reported against the cabal-install program:
The summary is that when using a round-robin proxy we get sporadic failures. The difference looks like:
In the failing case
X-Cache: HIT from wwwcache.lancs.ac.uk X-Cache-Lookup: HIT from wwwcache.lancs.ac.uk:8080 X-Cache: MISS from wwwcache.lancs.ac.uk X-Cache-Lookup: MISS from wwwcache.lancs.ac.uk:8080 Via: 1.0 wwwcache3.lancs.ac.uk:8080 (squid/2.6.STABLE22), 1.0 wwwcache1.lancs.ac.uk:8080 (squid/2.7.STABLE4) Connection: close
In the working case:
X-Cache: HIT from wwwcache.lancs.ac.uk X-Cache-Lookup: HIT from wwwcache.lancs.ac.uk:8080 Via: 1.0 wwwcache3.lancs.ac.uk:8080 (squid/2.6.STABLE22) Proxy-Connection: close
In particular in the failing case we get a cache hit followed by a mystery miss and finally Connection: close. In the working case we get no miss and a Proxy-Connection: close.
Why Connection: vs Proxy-Connection: we wonder, and what is this cache miss about?
