Then you just need to modify the data group to reflect that. Example:

"www.domain1.com" := "10.10.10.11 80"
"www.domain2.com" := "10.10.10.11 80"
"www.domain3.com" := "10.10.10.11 80"
"www.domain4.com" := "10.10.10.11 80"
...
"www.domain500.com" := "10.10.10.11 80"

"www.domain501.com" := "10.10.10.12 80"
"www.domain502.com" := "10.10.10.12 80"
"www.domain503.com" := "10.10.10.12 80"
"www.domain504.com" := "10.10.10.12 80"
...
"www.domain1010.com" := "10.10.10.12 80"

though I think at this point you should probably just use two pools:

"www.domain1.com" := "pool1"
"www.domain2.com" := "pool1"
"www.domain3.com" := "pool1"
"www.domain4.com" := "pool1"
...
"www.domain500.com" := "pool1"

"www.domain501.com" := "pool2"
"www.domain502.com" := "pool2"
"www.domain503.com" := "pool2"
"www.domain504.com" := "pool2"
...
"www.domain1010.com" := "pool2"

and then modify the iRule accordingly:

when HTTP_REQUEST {
    if { [class match [string tolower [HTTP::host]] equals my_domain_dg] } {
        pool [class match -value [string tolower [HTTP::host]] equals my_domain_dg]
    }
}
