Hi Wennie,
I may be getting the wrong end of the stick here, but It sounds like you are
asking how to load-balance traffic to and from a single host (squid box) over
two links that you only control on the near end, without touching the routers
involved.... that's quite a challenge.
One approach which has worked very well for me in the past is to use at least
two squid boxes, each associated to an address that is preferred on separate
links. You can then split your traffic across the two links by splitting your
traffic across the two squid boxes.
You could do this for proxy-configured clients by using a WPAD proxy script
which returns different PROXY strings based on the ip address of the client,
and for non-proxy-configured clients, by letting WCCP split the load (by
destination address hashes I think) as long as both squid boxes register with
the same intercepting router.
If you can involve your BGP config engineer, then you will have more options -
you can't talk about load balancing and redundancy without involving routing
anyway - you split the inbound traffic from the outbound traffic and then talk
about how you can influence the paths taken in each case.
Regards
Phi DG

Subject: [squid-users] Multiple ISP setup
How can I setup my squid to automatically connect and load balance from
two
or more ISP at the same time? Presently we are connected to ISP 1 so all
clients are served by our proxy server through ISP 1, now we are about
to
have ISP 2 my question now is how can I configure my squid to use both
ISP
at the same time, when ISP 1 is down all request will be on ISP 2 and
vice
versa?
The routing will be handle by our router configure for BGP, so my only
concern is about squid.
Thank you very much,
Wennie
