cookies - Are there HTTP headers that could reasonably be present multiple times? -


when @ list of standard http headers requests , responses on wikipedia (http://en.wikipedia.org/wiki/http_header), headers reasonable when occur once in request or response.

most. not all. cookie in request , set-cookie in response present multiple times when dealing multiple cookies set server or transmitted client.

when server wants set multiple cookies, there 1 set-cookie header each one. client presents these cookies 1 cookie header each.

apart of cookies: there other http headers present multiple times (in valid http request)?

http://tools.ietf.org/html/rfc2616#section-4.2

multiple message-header fields same field-name may present in message if , only if entire field-value header field defined comma-separated list [i.e., #(values)].
