Thanks alot Vernon! That is definitely enough to get me going!

Update: I have uploaded an html file "maint-page.html" via the GUI File Management-->iFile List-->import and have referenced the file in the following iRule:

when HTTP_REQUEST {
        HTTP::respond 503 content [ifile get maint-page.html]
}

However; when I go to apply the iRule to the VIP is states

Rule [/Common/irule_maint-page] error: Unable to find ifile (maint-page.html) referenced at line 2: [ifile get maint-page.html]

I have confirmed that the iFile is in the iFile list though. Any ideas? Thanks.
