code 206 - visible as '206' in varnishncsa and as '200' from VCL code

Hi Tollef,

Well, to my understanding, the way I read out the delivery status is  
already after vcl_deliver has run. The status collection routine is  
called as follows for each backend:

sub vcl_deliver {
     C{ STATS_UPDATE(www_somesitename_com) }C
}

So at this point all delivery statusses (stati?) should be known to  
Varnish. This setup has been running succesfully for several months  
and it works for all codes except 206. Am I missing something here?

'We' have a setup here where we have about 30 different sites, big and  
small, all running of a cluster of 3 Varnish servers and log and graph  
the returncodes and several other parameters of each site seperately.  
Not having proper registration of the 206 codes does create a hole in  
our logging, but it has not proven to be an issue yet, although we are  
aiming to have this hole closed some time in the near future.

Cheers,

Johnny
