Redirect Failure for iRule

A couple things that I noticed:

1. Looks like your first 2 if...elseif statements are the same (if the test it testssl.communigator.co.uk). I'd consolidate and use a single "switch -glob"

    

2. On you switch -glob looking at /Commons, Cory is right about checking needing to make that lowercase or it won't match, but the way you have it, it's looking for a path EXACTLY like "/common/". If you change it to "/common/*" (so it'll check that it starts with /common/ and could have something after that), that may help you out. (Not to mention if you wanted to prepend the /login/, you'd need to update the redirect to ...".co.uk/login[HTTP::uri]"

    

Does that help at all?

So the new code might look something like this:

when HTTP_REQUEST { 
    if { [HTTP::host] eq "testssl.communigatormail.co.uk" } { 
        switch -glob [string tolower [HTTP::path]] { 
            "/" { 
                HTTP::redirect "https://testssl.communigator.co.uk/login" 
                }
            "/common/*" { 
                HTTP::redirect "https://testssl.communigator.co.uk/login[HTTP::uri]" 
            }  
            default { 
                HTTP::redirect "https://testssl.communigator.co.uk/[HTTP::uri]" 
            }
        } 
    } elseif { [HTTP::host] eq "testssl.communigator.co.uk" } { 
        switch -glob [string tolower [HTTP::path]] { 
            "/login/" - 
            "/lz/*" { 
                HTTP::redirect "https://testssl.communigator.co.uk[HTTP::uri]" 
            } 
        }
    }
}
