HTTP::respond 403 content have you tried 200 instead of 403? 
Pankaj_70057yes same result getting blank page.
I also trien below irule very simple to set the massage and same result.
iRule:
when HTTP_REQUEST {
HTTP::respond 200 content {This website is currently under scheduled maintenance until 8AM CST on 1/19/2013!}
}
I am new to iRules so any help on this is really appreciated.
Thanks

have you run tcpdump to see what is going on?
tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x and host y.y.y.y
x.x.x.x is client ip address
y.y.y.y is virtual server ip address - Pankaj_70057I notice one more this iRule is working if i remove the http to https redirect iRule. we have below HTTP to HTTPS redirect iRule on all vertual servers.
i am not sure why this iRule create issue to maintenance massage iRule.
when HTTP_REQUEST {
HTTP::redirect "https://[getfield [HTTP::host] : 1][HTTP::uri]"
} - nitassi am not sure why this iRule create issue to maintenance massage iRule. have you checked /var/log/ltm? i understand you would get "Multiple redirect/respond invocations not allowed" error message.
