Status code

In the reports generated by CrawlForMe each link is associated to HTTP response status code. You will find in this page informations about the http status code. The most popular status are the code 200 for a successfull request and the code 404 for a page not found. But there are dozens of other codes.

See below the list of all status codes (links are used in the demo report)

Informational 1xx

This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. Since HTTP/1.0 did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 client except under experimental conditions.

Successful 2xx

This class of status codes indicates the action requested by the client was received, understood, accepted and processed successfully.

Redirection 3xx

This class of status code indicates that further action needs to be taken by the user agent to fulfill the request. The action required may be carried out by the user agent without interaction with the user if and only if the method used in the second request is GET or HEAD. A user agent should not automatically redirect a request more than five times, since such redirections usually indicate an infinite loop.

Client Error 4xx

The 4xx class of status code is intended for cases in which the client seems to have erred. Except when responding to a HEAD request, the server should include an entity containing an explanation of the error situation, and whether it is a temporary or permanent condition. These status codes are applicable to any request method. User agents should display any included entity to the user.

Server Error 5xx

Response status codes beginning with the digit "5" indicate cases in which the server is aware that it has encountered an error or is otherwise incapable of performing the request. Except when responding to a HEAD request, the server should include an entity containing an explanation of the error situation, and indicate whether it is a temporary or permanent condition. Likewise, user agents should display any included entity to the user. These response codes are applicable to any request method.
