Host a HTML Maintenance Page on LTM

Hi Yann, thanks for the Irule, our requirement is only to show maintenance page if the whole VIP is down i.e. none of the servers are operational.

So I guess I will just use the last condition in your iRule?

And also, how can we use a logo in the iFile? do I just import a picture directly as an iFile on f5?

SO BASICALLY I HAVE A HTML PAGE WITH LOGO AT THE TOP...I'M USING THE FOLLOWING IRULE:

when HTTP_REQUEST { if { [active_members [LB::server pool]] == 0 } { HTTP::respond 200 content [ifile get MAINTENANCE.html] "Content-Type" "text/html"

} }

SO WHEN ALL SERVERS ARE DOWN , IT'S DISPLAYING PAGE LIKE THIS:

&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&

WHAT IS THE FORMAT OF THE IFILE, WHAT FORMAT SHOULD I UPLOAD ON F5?

Hi,

To use ifiles, you should upload the html content in plain text in System >> Files

Then you need to declare a ifile name in The Local Traffic >> iRules >> iFiles section

and finally you can get the content of your ifile using the following command [ifile get MAINTENANCE.html]

Note that MAINTENANCE.html is the name of the ifile declaration previously done on Local Traffic >> iRules >> iFiles

thanks I did...I uploaded it as a text file, it worked.

But it's not displaying the logo on the Page which we have as a part of maintenance page.

How can we use logo and text together?

I tried this but didn't work:

when HTTP_REQUEST { if { [active_members [LB::server pool]] == 0 } { HTTP::respond 200 content [ifile get maintenance.html] "Content-Type" "text/html" and [ifile get logo.png] "Content-Type" "image/gif"

} }

Hi,

you have to follow how I built my irule for maintenance. in the maintenance.html file, you should have a reference to the logo like this :

and your irule should looks like this :

when HTTP_REQUEST {
    if { [active_members $default_pool] < 1 } { 
        HTTP::respond 200 content [ifile get "/Common/maintenance.html"] noserver "Content-Type" "text/html" "Cache-Control" "no-cache, must-revalidate" 
        return
    }

    if { [string tolower [HTTP::path]] equals "/logo.png" } {
            HTTP::respond 200 content [ifile get "/Common/logo.png"] noserver "Content-Type" "image/png" "Cache-Control" "no-cache, must-revalidate" 
    }
} 

I tried this but didn't work..... for the logo I still see a 'X' there.

Why are you using '/Common' before the iFile like /Common/logo.png.

Is there any other way to provide reference to the logo? like I don't want to use another 'If' statement. Can it be integrated in one 'if' statement - both Image and HTML?

Like if I use only logo IF statement, it works and if I use only HTML IF statement, it works but if I use both together, Image doesn't come up.

Any help??
