Phil Sorber commented on TS-1510:
---------------------------------
With the latest master I am able to cache large objects and retrieve them.
First request:
{noformat}
-bash-4.1$ curl -v -4 -o /dev/null http://proxyhost/Fedora-19-x86_64-DVD.iso
* About to connect() to proxyhost port 80 (#0)

Then the second request that pulls from cache:
{noformat}

Here is the related server debug output:
{noformat}
[Jul 24 17:13:09.318] Server {0x7fc85aaa4700} DEBUG: (http_cache_write) [5]
writing to cache with URL http://127.0.0.1:8080/Fedora-19-x86_64-DVD.iso

I am going to mark this as not reproducible. If there is some new information
that makes his more reproducible then please re-open.

> Project: Traffic Server
> Issue Type: Bug
> Components: Cache
> Affects Versions: 3.3.0
> Environment: Ubuntu 10.04 and 12.04
> Reporter: Kingsley Foreman
> Assignee: Phil Sorber
> Labels: A
> Fix For: 3.3.5
>
>
> 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.
