#Middleware in Laravel 5
Middleware is a powerful feature of Laravel 5. In this talk, we'll briefly cover what middleware is, it's place in the Laravel lifecycle, and how to create it. Then we'll look at some real-world, in-production use cases that demonstrate the appropriate use of middleware to examine incoming requests, and situations where you might modify the out-going response headers or body content. Finally, you'll learn some use-cases where not to use middleware, and how to test it. Phillip is a web developer with 16 years of experience currently building solutions with Laravel for Cisco Systems, Inc.'s Learning@Cisco team.
If I was using Lavarel, I might be interested in this talk, especially since you also mention disadvantages which is quite rare (but very welcome). I do agree with Chris that you need to pitch the topic more. Maybe a catchier title? Or mention why exactly middleware is a "powerful feature" (or maybe even mandatory)? Or better use cases (as far as I can read from the abstract, you just work with the request and the response, which kinda is the same case)?
Also, do remove the bio. Most conferences have a separate field for that in their call for papers. The bio doesn't help the abstract.
