Deliver while caching

We need to serve videos from varnish, but the problem is that it deliver
the file untill it finish caching it, so if the file weight 500Mb, the
client will have to wait around 1 minute in order to varnish to cached it,
and then varnish will start the deliver to the client.

Is there any way to deliver the file while it is being cached?

Re: Deliver while caching [In reply to]

hi,

> Is there any way to deliver the file while it is being cached?

you can use return(pipe) for these requests (if you can deduce from the
url what they are). that should work. i do not know, whether there are
better ways.

Re: Deliver while caching [In reply to]

I have varnish 3.

me [at] ibotty suggest me to use return (pipe). That is the way to stream
the content?

There's a branch with streaming support. The standard 3.0.2 release does not
contain those patches. See
https://www.varnish-software.com/blog/http-streaming-varnish for more info.

Re: Deliver while caching [In reply to]

If I used pipe, the content is not cached, am I right?

Re: Deliver while caching [In reply to]

So then, there is no way I can do what I want? Deliver while caching and
keep that in cache?

No it's not. It talks about limited streaming support in 3.0.2: only one client
can stream an object. But 3.0.2s (note the s, denoting a streaming release) is
a release of the streaming branch, which supports more than one client.

The post doesn't say so. It only states that the code will be merged with
the 3.0 branch. The result is in the 3.0.2s release.

Use the 3.0.2s release. repo.varnish-cache.org/test/ has some packages.

Seriously, please take the effort to quote properly. Outlook-style quoting
doesn't really work well in a thread with multiple issue. Also; yes.
