Irule to block access of VS on specific days

Stan,

Thanks for the rule, but in your rule the Second condition when HTTP_REQUEST is not being executed. i have created the below rule which is working fine but i need to add one more condition (if { ( [class match [IP::remote_addr] equals clntip]). this condition when i add in the below rule it is not working, remaining the rule is working fine.

Kindly advice.

when RULE_INIT {
    set static::START_OFF_TIME [clock scan "05:30 AM"]
    set static::END_OFF_TIME [clock scan "04:00 PM"]
}

when HTTP_REQUEST {
    set now [clock seconds]
    set current_day [clock format [clock seconds] -format {%u}] }

    if { not ([string tolower [HTTP::uri]] contains "/contracts/")  } { 
        pool POOL_443 
        }
     elseif { ([class match [IP::remote_addr] equals clntip]) && ([string tolower [HTTP::uri]] contains "/contracts/") && ($current_day >= 1 )  && ($current_day < 4 ) && ( $now > $static::START_OFF_TIME ) && ( $now < $static::END_OFF_TIME ) } {
        pool POOL_443
        }
    elseif { ([class match [IP::remote_addr] equals clntip]) && ([string tolower [HTTP::uri]] contains "/contracts/") && ($current_day == 7 ) && ( $now > $static::START_OFF_TIME ) && ( $now < $static::END_OFF_TIME ) && ( [class match [IP::remote_addr] equals clntip]) } {
        pool POOL_443
        }
    elseif { ([string tolower [HTTP::uri]] contains "/contracts/") && ($current_day == 5 ) or ($current_day == 6 ) } {
        HTTP::respond 200 content "Weekend!Its a Weekend! Contact Administrator..."
        }   
 else {
        HTTP::respond 200 content "Not Authorised!Not Authorised! Contact Administrator..."
}

}
