--------------------------------------
Ok an update on this, it appears it isn't going into cache correctly. This
file is 1.8gb, and the cache is mostly empty (spare 1TB)
I've done a bit of testing, and things look a little like this
[Jan 24 09:09:16.758] Server {0x2adf1b819700} DEBUG: (http_cache_write) [59]
writing to cache with URL
http://127.0.0.1:8081/20022/depot/209541/chunk/bd4874c63dfe699dcec21da7efe31930c73334f9

So for some reason it isn't going into cache correctly.

> URL: https://issues.apache.org/jira/browse/TS-1510
> Project: Traffic Server
> Issue Type: Bug
> Components: Cache
> Affects Versions: 3.3.0
> Environment: Ubuntu 10.04 and 12.04
> Reporter: Kingsley Foreman
> Fix For: 3.3.3
>
>
> With an empty cache of 120gb.
> I've added two files.
> 1. 2mb file
> 2. 3gb file.
> after 30min
> 2mb file remains in cache rechecks home (304) serves from cache
> 3gb file not i cache, and does a 200 request from the origin server like it
> has been cleared from cache.
> There is plenty of space so it isn't expiring, so really it should do a 304
> not a 200 to the origin server.
