Load Balancing to Casches

are you using v10? if so, just wonder why you do not just use built-in carp.

 

 

sol11362: Overview of the CARP hash algorithm

Thanks , does this achive Top Domain selection ?

 

 

also it mentions the Irule :

 

when HTTP_REQUEST {

 

persist hash [HTTP::uri]

 

}

 

 

This persists based on the URI , my target is to persist based on the site ( all tarffic of youtube to go to same cache ........ ) , what is the IRule for that ?

 

you can use [HTTP::host] instead of [HTTP::uri].

Thanks alot , what about meaning / benefit of " Top Domain selection" ?

i guess you mean to load balance by using part of FQDN. if so, yes it is possible. you can specify any part of FQDN when doing CARP i.e. replace [HTTP::host] with whatever you want.
