<meta http-equiv="Reply-to" content="admin@example.com" />

There does not seem to a “Reply-to” equivalent header in HTTP. Should I remove it or correct it?

    I am not sure ‘Reply-to’ is still valid. It’s not listed in the Sitepoint Reference. However, there is an ancient W3C spec that says:

    HTTP servers may read the content of the document HEAD to generate header fields corresponding to any elements defining a value for the attribute HTTP-EQUIV. (14)

    […]

    If the document contains:

    <META HTTP-EQUIV="Expires" CONTENT="Tue, 04 Dec 1993 21:29:02 GMT">
    <meta http-equiv="Keywords" CONTENT="Fred">
    <META HTTP-EQUIV="Reply-to" content="fielding@ics.uci.edu (Roy Fielding)">
    <Meta Http-equiv="Keywords" CONTENT=”Barney”>`

    then the server may include the
    following header fields:

    Expires: Tue, 04 Dec 1993 21:29:02 GMT
    Keywords: Fred, Barney
    Reply-to: fielding@ics.uci.edu (Roy Fielding)
