MVPJust to clarify, you are looking for a maintenance page? When you say 'banner', it makes me think that you want to inject javascript or somerthing and put a banner atop the normally loaded page that provides an alert. That would be a separate and more difficult requirement of course. Simple maintenace page is no issues, and you can even store the HTML page, JS, and any images on the F5 itself using iFiles. Just some further thoughts here.

AltocumulusHi Whisperer,
Thanks for response.
I am putting maintenance page. I tried to put simple html page or message. Also tried to put html page via ifile (HTTP::respond 200 content [ifile get "maintenance_Page"] even it is not working for me.
when HTTP_REQUEST {
if { ([HTTP::uri] starts_with "/example")
HTTP::respond 200 content {
<html>
<head>
<title>Apology Page</title>
</head>
<body>
We are sorry, but the site you are looking for is temporarily out of service<br>
If you feel you have reached this page in error, please try again.
</body>
</html>
}
}
}

Can you provide the output for the Virtual Server object? Also, what URL are you testing with in the web browser?

Hi ,
I found the issue. There are two irule applied on VIP. First irule mainentance page and second irule to set same site cookie as none .
In Packet capture i saw irule exceution error. First irule for mainentance page when http request is matching and it is responding to 200 with maintenece page.
when second irule is exceuting, it is the http response release to set same site cookie as none as first irule is already executed with response. It is failing.
For testing i have removed second irule(same site cookie), it is working.
Just want to know if below same site irule is feasible via LTM policy or other solution.
same site irule-
when HTTP_RESPONSE_RELEASE {
set cookie_names [HTTP::cookie names]
foreach a_cookie $cookie_names
{
if {not [HTTP::cookie attribute $a_cookie exists {SameSite}] }
{HTTP::cookie attribute $a_cookie insert "SameSite" "None"}
}
}

Regarding LTM policies, They may not have the same level of granularity in event triggers as iRules, which can be triggered at various stages of traffic processing. You may need to stick with iRule in your case.
