Translate mod_rewrite to iRules

You need to enable SSL bridging on you virtual server, and then try this:

when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] ends_with ".abc.domain.com" } {
        switch -glob [string tolower [HTTP::uri]] {
            "*lib/*"  {
                          HTTP::redirect "http://my-error-page-server/"
            }
            "*static_pages/*" {
                          HTTP::redirect "http://my-error-page-server/"
            }
            "*assets/*"  {
                          HTTP::redirect "http://my-error-page-server/"
            }
            default {
                        HTTP::header replace Host "abc.domain.com"
                        HTTP::uri /test/[HTTP::host]/[HTTP::uri]
                        node 1.2.3.4  IP addr of backend server.
        }
    }
}
