What kind of grammar is this: "Set-Cookie:" Name "=" Value *(";" Attribute)

It doesn't look like any of the BNF family. I have seen this in several RFC papers, for example HTML 1.1, but it is never explained. I can't find anything other than formatting guidelines on the RFC site either

Solution

  • It is an "augmented BNF" as explained in http://www.w3.org/Protocols/rfc2616/rfc2616-sec2.html.
