 # No Post Data Laravel Middleware
 
+Under certain conditions, when posting data from a form, the web server may loose the post data. This commonly happens if a user is uploading a large 
+file beyond the size limits set in the web server's configuration.
+
+Laravel does not handle this situation and may end up throwing a somewhat confusing `TokenMismatchException in VerifyCsrfToken` due to CSRF protection.
+
+The 'No Post Data Laravel Middleware' handles situations in which a request a post request has been submitted and contains no post data - a situation 
+which should not occur under normal usage. By default, the middleware will redirect back to the previous page with an error message flashed to the 
+session. This can then be output on your view as you would normally handle validation errors.
+
+If needed, you can also modify this default behaviour and allow any code to run when the 'post request with no post data' situation is encountered.
