HTTP10

HTTP10 is a term that does not designate a formal protocol standard. In most contexts it is either a mistaken reference to HTTP/1.0 or an informal label used for non-standard, experimental variants of the Hypertext Transfer Protocol. There is no RFC or widely adopted specification officially named HTTP10.

Because there is no official specification, implementations or documents that use the label HTTP10 can vary and may not interoperate. When encountered in historical or experimental material, it is important to determine whether the author meant HTTP/1.0 or a specific non-standard extension.

HTTP/1.0 introduced a simple request/response model, where each request generally opened a new connection. Subsequent revisions standardized features such as persistent connections and more robust caching in HTTP/1.1. Proposals labelled HTTP10 in some discussions often attempted to address perceived limitations of early HTTP, but none gained formal acceptance as a separate protocol.

Today, references to HTTP10 are rare and typically discouraged in favor of precise terminology (HTTP/1.0, HTTP/1.1, or other protocol implementations). Users and developers are advised to rely on established nomenclature to avoid ambiguity.
