When a RequestDataTooBig exception is thrown, users are largely in the dark about what happened and how it can be fixed. This commit resolves this by inserting middleware to redirect the request to a custom 413 error page. This exception is thrown when DATA_UPLOAD_MAX_MEMORY_SIZE is exceeded. The default value is 2.5MB. Fixes #2340 Fixes #2633
