HTTP redirection irule

You're iRule might look something like this:

when HTTP_REQUEST {
    switch [string tolower "[HTTP::host][HTTP::uri]"] {
        "abc.com/" -
        "www.abc.com/" {
            HTTP::redirect "/us/en/product-solutions/transportation/find-a-cellphone-pc.aspx"
            return
        }
    }
}

The other option (if you're using v11.4 or greater) is Local Traffic Policies. Simple actions (including redirects) can be done there and may be simpler to configure if you're not used to iRules. This question has an example that might guide you in the right direction if you wanted to do it that way.
