Fix Error Codes

  A 400 Bad Request, also known as a   400 error   or   HTTP error 400 , is perceived by the server as a generic client error and it is returned when the server determines the error doesn’t fall in any of the other status code categories. The key concept to understand here is that the 400 Bad Request error is something that has to do with the submitted request from the client  before  it is even processed by the server. The Internet Engineering Task Force (IETF) defines the  400 Bad Request  as: The 400 (Bad Request) status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing). What Causes the HTTP 400 Bad Request Error There are various root causes that can trigger the 400 Bad Request error and, even if this error isn’t specific to any particular browser or OS (operating system), the fixes do vary slightly. 1.
