[PATCH] backend conditional requests first release

[Dmitry Panov]

Hi Geoff,

Thanks for the patch. I have tried it and it appears to be working. I've 
just spotted one problem so far: it looks like the gziped flag is not 
copied from the stale object it is possible to serve gziped object to a 
client that doesn't support it. I'm new to varnish and I'm not familiar 
with the code yet, but the following patch solved the problem for me:

+                sp->obj->gziped = o_stale->gziped;

                  break;
