What is RESTful actually

1 year, 10 months ago
And your application — RESTful? To answer this question it is necessary to understand at first that such RESTful. There is an opinion that to give the correct codes of answers to HTTP is already RESTful. Or to do the correct idempotent HTTP requests is in general very much RESTful. We in Heksleta made a practical course under the HTTP protocol (differences of versions, sending forms, authentication, cookies and so forth), and in it we try to tell about the correct use of requests, but it is necessary to understand that RESTful it not about HTTP, it at all not about internet protocols. The modern web and interaction between the browser and the server by means of HTTP and URI can satisfy to the principles of RESTful, and can not satisfy.

1 year, 10 months ago
I solved on the example of one project recently to learn, how strongly influences the speed of loading of the website domain sharding. I will remind, an essence of this optimization that static files are loaded from different domains (which, however, can indicate the same server), and it allows to bypass restriction of browsers for the number of simultaneous connections to one domain.
