Author: phk

New Revision: 5461

Added:
   trunk/varnish-cache/bin/varnishtest/tests/r00801.vtc
Modified:
   trunk/varnish-cache/bin/varnishd/cache_fetch.c
Log:
On pass (from vcl_recv) we did not remove the backends Content-Length 
header before adding our own.

We can not do this with the fetch filtering, because pass might send
HEAD requests to the backend.

XXX: It's arguable that the filtering stuff might be better done
inline than with a table.

Fixes: #801
