iRule with Client Detection

My Code right now:

when RULE_INIT {
set static::maxloginfailures 10
set static::bantime 200
set static::blacklist_tab  "IPBlacklist"
set static::userfail_tab   "LoginFailures"
}

when CLIENT_ACCEPTED {
set clientip [IP::client_addr]
set client_UserAgent [ACCESS::session data get session.user.agent]
set client_Platform [ACCESS::session data get session.client.platform]
if { [table lookup -subtable $static::blacklist_tab $clientip] == 1 } {
    reject
    return
} }

when AUTH_FAILURE {
if {[table lookup -subtable $static::userfail_tab $clientip] > $static::maxloginfailures} then {
table set -subtable $static::blacklist_tab $clientip 0 indef $static::bantime 
table delete -subtable $static::userfail_tab $clientip
}
if { [table lookup -subtable $static::userfail_tab $clientip] != 1 } then {
table set -subtable $static::userfail_tab $clientip 0 indef indef
} else {
table incr -subtable $static::userfail_tab $clientip 
}
}

when AUTH_Success {
table delete -subtable $static::userfail_tab $clientip
}
