["Kingsley Foreman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-1510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13561195#comment-13561195 ] 

Kingsley Foreman commented on TS-1510:
--------------------------------------

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.

> 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.
