ACE best practice for proxy servers

pemalcoun · ‎07-29-2012

Dear,

I would like to know which is the best practice scenario to load balance proxy servers:

1- Best practice to have transparent proxy or proxy setting on the web browser?

2- for transparent proxy: best practice to use ip wccp or route-map pointing to the ACE VIP?

3- What are the advantages and disadvantages of transparent proxy V/S web browser proxy setting.

Regards,

Pierre

Hi,

It depends on your requirement. The one advantage of using using PBR - would provide the flexibility of only directing traffic which needs to be load balanced to cache servers and dont need to send all traffic to ACE.

Hi,

Sorry, that seem to be an internal link.

You can also check the below post where a sample config is posted here for transparent cache.

Best practice :

VIP would be a catch all address.

To optimize the caching predictor hash url is used.

You can also use mac-sticky on interface so proper flow persistence is used within ACE

The mode is transparent so we preserve the destination ip address.
