the 1.2 version stable enough so i can use this last one ?

 Actually, we are heading into the 2.0 release cycle, so you should
 grab a -trunk copy from SVN and look at that.

 The first 2.0 release preview will be rolled real soon now.

Using Range requests with cached files

[Oliver Oli]

Hello,

how does varnish handle Range request? I'm getting varying results.
Sometimes it seems that a Range request is delivered from the cache,
sometimes it seems that varnish is receiving the whole file from the
backend first and sometimes it serves the whole file completely
ignoring the Range header. I cannot see any pattern in varnish's
behaviour.

Does vernish support the Range header at all?

I'm using the default.vcl from the debian package (built from the 1.2
branch) with set obj.ttl=30d in sub vcl_fetch.

Re: Using Range requests with cached files

[Oliver Oli]

Hello Poul-Henning,

good to know. Is there a way to cache partial responses anyway
(ignoring the fact that many requests for differing ranges would blow
up the cache)? I tried to add req.http.Range to req.hash, but I'm
oviously missing something, because it's not cached.

sub vcl_hash {
set req.hash += req.url;
set req.hash += req.http.Range;
set req.hash += req.http.host;
hash;
}

Flash Range header workaround?

[Oliver Oli]

Hello,

I haven't found any user manual on the Varnish website... it seems to
me that varnish is quite flexible, but i don't know where to start.
Any pointer to some documentation / tutorial is welcome.

I have a simple use case:
I would like to request a partial document from a Flash movie [1].
Unfortunatly the Range header is blocked by flash. I wonder if I can
use Varnish for a work-around. like rewriting

http://varnish.localhost/mysong.mp3?range=1-3

to

http://backend.localhost/mysong.mp3
and a Range: bytes=1-3 header

or rewriting some custom X-Oli-Range:  header to Range: 


Is Varnish able to cache partial documents?

- Oli
