This optional header provides an indication of the poster's intent regarding preservation of the article in publicly accessible long- term or permanent storage.
Archive-content = [CFWS] ("no" | "yes" ) [CFWS] Archive-header-parameter = Filename-token "=" value ; for USENET-header-parameters see 4.1 Filename-token = [CFWS] "filename" [CFWS]
The presence of an "Archive: no" header in an article indicates that the poster does not permit redistribution from publicly accessible long-term or permanent archives. The absence of this header, or an explicit "Archive: yes", indicates that the poster is willing for such redistribution to take place. The optional Filename parameter can then be used to suggest a filename under which the article should be stored. Further extensions to this standard may provide additional parameters for administration of the archiving process.
NOTE: This standard does not attempt to define the length of "long-term", since it is dependent on many factors, including the retention policies of individual sites, and the customs or policies established for particular newsgroup or hierarchies.
NOTE: Posters are cautioned that some sites may not implement the "no" option of the Archive header correctly. In some jurisdictions non-compliance with this header may constitute a breach of copyright or of other legal provisions. Moreover, even if this header prevents the poster's words from being archived publicly, it does nothing to prevent the archiving of a followup in which those words are quoted.
