All Implemented Interfaces:

Comparable

Deprecated.

Jakarta Commons HttpClient 3.x is deprecated in the Jenkins project. It is not recommended to use it in any new code. Instead, use HTTP client API plugins as a dependency in your code. E.g. Apache HttpComponents Client API 4.x Plugin or Async HTTP Client Plugin.

@Deprecated
public class HttpVersion
extends Object
implements Comparable

HTTP version, as specified in RFC 2616.

HTTP uses a "<major>.<minor>" numbering scheme to indicate versions of the protocol. The protocol versioning policy is intended to allow the sender to indicate the format of a message and its capacity for understanding further HTTP communication, rather than the features obtained via that communication. No change is made to the version number for the addition of message components which do not affect communication behavior or which only add to extensible field values. The <minor> number is incremented when the changes made to the protocol add features which do not change the general message parsing algorithm, but which may add to the message semantics and imply additional capabilities of the sender. The <major> number is incremented when the format of a message within the protocol is changed. See RFC 2145 [36] for a fuller explanation.

The version of an HTTP message is indicated by an HTTP-Version field in the first line of the message.

     HTTP-Version   = "HTTP" "/" 1*DIGIT "." 1*DIGIT
  

Note that the major and minor numbers MUST be treated as separate integers and that each MAY be incremented higher than a single digit. Thus, HTTP/2.4 is a lower version than HTTP/2.13, which in turn is lower than HTTP/12.3. Leading zeros MUST be ignored by recipients and MUST NOT be sent.
