HTTP Redis, SSI and error log

[vchav]

> What is the $key?
set $redis_key "$http_host$document_uri$query_string";

> Provide more information about redisbackend
> description.

upstream redisbackend {
      server 127.0.0.1:6379;
      keepalive 256 single;
}

Additional information : I've removed the line
static ngx_str_t  ngx_http_redis_db  = ngx_string("redis_db");

Because of error in compilation.
./configure ... --add-module=../ngx_http_redis-0.3.2
--add-module=../ngx_http_upstream_keepalive-c6396fef9295
make && make install

Thanks you
