Hi Mbarreau,

I'd prefer the 

switch
command to parse the requested 
HTTP::host
value for 
pool
selection.

when HTTP_REQUEST {
    switch -exact -- [string tolower [HTTP::host]] {
        "site1.domain.de" {
            pool pool_1
        }
        "site2.domain.de" {
            pool pool_2
        }
        "site3.domain.de" {
            pool pool_3
        }
        "site4.domain.de" {
            pool pool_4
        }
    }
}

Note: The the example above uses a 

[string tolower [HTTP::host]]
command to ignore the case during evaluation. It helps to make the pool selection more robust...

Cheers, Kai
