How to make HAProxy redirect traffic via a certain sub-proxy depending on URL? in c/programming@programming.dev
[–] maximalian@sopuli.xyz 2 points 4 months ago* (last edited 4 months ago) (1 children)

There're 2 conditions in my question. In the links the solutions described are partial, though. A part of a part. That is, "how to identify a keyword", "how to redirect if ...".

But how to actually put them all together? For instance, how to merge "if a keyword then redirect via a pre-specified, random sub-proxy"? How to them add into all that "otherwise, use no proxy"?

  1. client -> HaProxy -> if keyword --> sub-proxy (random) -> website
  2. client -> HaProxy -> if no keyword --> website

I have a server (S-1) with HAProxy and a number of residential proxies (PR-s) as login-passwords-port. There're multiple users who will connect to the internet via S-1.

I want to have HAProxy to forward incomming traffic of the users via a random proxy amoung PR-s with 2 conditions:

  1. only when there's certain, pre-defined keyword in the URL, traffic must be routed via a proxy.
  2. In all other cases, it must go to a requested resource directly as is, without a proxy

How would I implement this?

(1) client -> HaProxy -> if keyword --> sub-proxy (random) -> website

(2) client -> HaProxy -> if no keyword --> website

In Squid config, is there any variable - %VAR - that contains the current unique request id or anything similar?

I'll need to pass that into an external script, for instance:

# squi.conf
auth_param basic program %REQUEST_ID(???) /etc/squid/my_auth.py

This may not be an authentication script, this is just an example.

I've searched but haven't found anything about it.

How to report back to Squid which peer to use? (sopuli.xyz)
 

Let's say, I have a python script which handles ACL:

#squid.conf
# [............]

# sub-proxies/peers
cache_peer 01.01.01.99 parent 34433 0 no-query no-digest name=peer1
cache_peer 01.01.02.99 parent 34433 0 no-query no-digest name=peer2
cache_peer 01.01.03.99 parent 34433 0 no-query no-digest name=peer3
cache_peer 01.01.04.99 parent 34433 0 no-query no-digest name=peer4


external_acl_type my_acl_helper ttl=30 %LOGIN ./my_acl_helper.py
acl session_acl external my_acl_helper

# [............]

In my_acl_helper.py there's some tricky logic of selecting a peer to be used for a request.

How should my_acl_helper.py report back to Squid which peer it's choosen? In what format? As far as I've found out, it could only be OK or ERR. But the IP:port or the alias of a peer will be needed as well. How?
