Possible to put parameter from an URL into a cookie?

If anyone interested, I found the solution:

when HTTP_REQUEST {

set param_domain [domain [HTTP::host] 2]
set param_wlw_comid [URI::query [string tolower [HTTP::uri]] comid]
set param_wlw_cusid [URI::query [string tolower [HTTP::uri]] cusid]

}

when HTTP_RESPONSE {

if { ($param_wlw_comid ne "") and ($param_domain ne "") }{
    HTTP::cookie insert name wlw_comid value $param_wlw_comid path "/" domain $param_domain
    HTTP::cookie expires wlw_comid 31557600
}

if { $param_wlw_cusid ne "" and ($param_domain ne "") }{
    HTTP::cookie insert name wlw_cusid value $param_wlw_cusid path "/" domain $param_domain
    HTTP::cookie expires wlw_cusid 31557600
}

}
