http_file_add_mime_types = { ["txt"] = "text/plain", ["png"] = "image/png",["jpg"] = "image/jpg", ["pdf"] = "application/pdf", ["doc"] = "application/msword", ["htm"] = "text/html", ["html"] = "text/html", ["mp3"] = "audio/mpeg3", ["gif"] = "image/gif", ["mp4"] = "video/mp4", ["mpeg"] = "video/mpeg", ["m4a"] = "audio/m4a", ["ogg"] = "application/ogg", ["gpx"] = "application/gpx+xml", ["vcf"] = "text/vcard", ["ics"] = "text/calendar", ["sxw"] = "application/vnd.sun.xml.writer", ["stw"] = "application/vnd.sun.xml.writer.template", ["sxg"] = "application/vnd.sun.xml.writer.global", ["sdw"] = "application/vnd.stardivision.writer", ["vor"] = "application/vnd.stardivision.writer", ["sgl"] = "application/vnd.stardivision.writer-global", ["sxc"] = "application/vnd.sun.xml.calc", ["stc"] = "application/vnd.sun.xml.calc.template", ["sdc"] = "application/vnd.stardivision.calc", ["sxi"] = "application/vnd.sun.xml.impress", ["sti"] = "application/vnd.sun.xml.impress.template", ["sdd"] = "application/vnd.stardivision.impress", ["sdp"] = "application/vnd.stardivision.impress", ["sxd"] = "application/vnd.sun.xml.draw", ["std"] = "application/vnd.sun.xml.draw.template", ["sda"] = "application/vnd.stardivision.draw", ["sxm"] = "application/vnd.sun.xml.math", ["smf"] = "application/vnd.stardivision.math", ["odt"] = "application/vnd.oasis.opendocument.text", ["ott"] = "application/vnd.oasis.opendocument.text-template", ["oth"] = "application/vnd.oasis.opendocument.text-web", ["odm"] = "application/vnd.oasis.opendocument.text-master", ["odg"] = "application/vnd.oasis.opendocument.graphics", ["otg"] = "application/vnd.oasis.opendocument.graphics-template", ["odp"] = "application/vnd.oasis.opendocument.presentation", ["otp"] = "application/vnd.oasis.opendocument.presentation-template", ["ods"] = "application/vnd.oasis.opendocument.spreadsheet", ["ots"] = "application/vnd.oasis.opendocument.spreadsheet-template", ["odc"] = "application/vnd.oasis.opendocument.chart", ["odf"] = "application/vnd.oasis.opendocument.formula", ["odb"] = "application/vnd.oasis.opendocument.database", ["odi"] = "application/vnd.oasis.opendocument.image" }
The difference is add instead of allowed.
