Five Common HTTP Status Code Errors

“As you know, HTTP stands for Hypertext Transfer Protocol (HTTP). All HTTP response status codes are separated into five classes or categories. The first digit of the status-code defines the class of response, while the last two digits do not have any classifying or categorization role.

Here are five classes defined by the standard:

  • 1xx informational response – the request was received, continuing process
  • 2xx successful – the request was successfully received, understood, and accepted
  • 3xx redirection – further action needs to be taken in order to complete the request
  • 4xx client error – the request contains bad syntax or cannot be fulfilled
  • 5xx server error – the server failed to fulfill an apparently valid request”
