Will caching work for forward proxy?
I try use Nuster as cache proxy for external forward proxy. But cache not saved on disk.
global
nuster manager on
master-worker
nuster cache on data-size 1m dir /tmp/nuster clean-temp off
nuster nosql off
defaults
mode http
timeout client 30s
timeout connect 30s
timeout server 30s
http-reuse always
frontend fe
mode http
bind *:8080
default_backend forward_proxy
backend forward_proxy
#mode http
option http-buffer-request
nuster cache on dir /tmp/nuster
http-response set-header X-Nuster-Cache ON
server s1 XXX.XXX.XXX.XXX:XXXXX
Proxy works but directory /tmp/nuster
is always empty.
What am I doing wrong? Thanks.
Can you check debug info?
I suspect that there is no way to cache transit traffic in the middle between the client and the parent proxy. I'm a bit confused about network theory.. As I understand it, if you specify an external forward proxy server (for example, Luminati / Bright Data) as a backend, then nuster / haproxy will simply proxy the HTTP CONNECT method. And nuster/haproxy will not cache redirected traffic. Is this a correct guess? Or am I still wrong, and is it possible to configure nuster / haproxy to cache traffic in front of another external proxy, being in the middle of the chain from the client to the external proxy? I use nuster as forward proxy-server for many sites:
curl -x my_nuster_proxy:8080 https://2ip.fun
The cache is not saved with this use of the nuster server. Do you still want to see the debug log? Thanks.
