The request should not be repeated. 404 Not Found The requested resource could not be found but may be available in the future.
In the context of an HTTP transaction, basic access authentication is a method for an HTTP user agent (e.g. a web browser) to provide a user name and password when making a request. In basic HTTP authentication, a request contains a header field in the form of Authorization: Basic <credentials> , where <credentials> is the Base64 encoding of ID ...
Under HTTP 1.0, connections should always be closed by the server after sending the response. [1]Since at least late 1995, [2] developers of popular products (browsers, web servers, etc.) using HTTP/1.0, started to add an unofficial extension (to the protocol) named "keep-alive" in order to allow the reuse of a connection for multiple requests/responses.
Laravel 1 included built-in support for authentication, localisation, models, views, sessions, routing and other mechanisms, but lacked support for controllers that prevented it from being a true MVC framework.

ARC-Authentication-Results (abbreviated AAR) - A combination of an instance number (i) and the results of the SPF, DKIM, and DMARC validation ARC-Seal (abbreviated AS ) - A combination of an instance number (i), a DKIM-like signature of the previous ARC-Seal headers, and the validity of the prior ARC entries.
It is a practical solution against any possible form of return-oriented programming. The solution eliminates all unaligned free-branch instructions (instructions like RET or CALL which attackers can use to change control flow) inside a binary executable, and protects the free-branch instructions from being used by an attacker.
If that fails, resend the frame after either 0 s, 51.2 μs, 102.4 μs, or 153.6 μs. If that still fails, resend the frame after k · 51.2 μs, where k is a random integer between 0 and 2 3 − 1. For further failures, after the cth failed attempt, resend the frame after k · 51.2 μs, where k is a random integer between 0 and 2 c − 1.
