Domain Redirect iRule

The equals operator doesn't support a wildcard match. But nevertheless:

} elseif { not ( [HTTP::uri] equals "/" ) } { 
    HTTP::respond 301 Location "http://www.blah.com[HTTP::uri]" 
} 

would create an infinite loop for any traffic that wasn't just "/". Important to observe of course that in the absence of a URI path in the browser, HTTP::uri will still return "/". So the first iRule didn't work?

when HTTP_REQUEST {
    if { [HTTP::uri] equals "/" } {
        HTTP::redirect ...
    }
}

This explicitly states that if the URI path is nothing/empty, then redirect, and implies that anything else be allowed through. You may otherwise not be meeting the HTTP::host qualifications.

Hi, there are multiple syntax errors in the irule.

try the following irules:

when HTTP_REQUEST { 
    Domain 301 Redirect 
    if { ([HTTP::host] equals "www.blah.com" ) or ([HTTP::host] equals "10.10.10.10") or ([HTTP::host] equals "blah.com") } { 
        if { ([HTTP::uri] equals "/") } { 
            HTTP::respond 301 Location "http://www.blah.com/home/index.jsp"
        } elseif { !([HTTP::host] equals "www.blah.com") } { 
            HTTP::respond 301 Location "http://www.blah.com[HTTP::uri]
        } 
    }
}

or use a switch command:

when HTTP_REQUEST { 
    switch -glob [string to lower [HTTP::host][HTTP::path]] {
        "www.blah.com/" -
        "blah.com/" -
        "10.10.10.10/" {HTTP::respond 301 Location "http://www.blah.com/home/index.jsp"}
        "blah.com/*" -
        "10.10.10.10/*" {HTTP::respond 301 Location "http://www.blah.com[HTTP::uri]"}
    }
}
