No, it does not matter for headers with different names. See RFC 2616, section 4.2: The order in which header fields with differing field names are received is not significant. However, it is “good practice” to send general-header fields first, followed by request-header or response- header fields, and ending with the entity-header fields. It DOES … Read more
Content-Language, an entity header, is used to describe the language(s) intended for the audience, so that it allows a user to differentiate according to the users’ own preferred language.

Cache-Control was introduced in HTTP/1.1 and offers more options than Expires. They can be used to accomplish the same thing but the data value for Expires is an HTTP date whereas Cache-Control max-age lets you specify a relative amount of time so you could specify “X hours after the page was requested”. HTML Cache control … Read more
Neither restclient nor REST console support this but curl does. The original HTTP 1.1 specification says in section 4.3 A message-body MUST NOT be included in a request if the specification of the request method (section 5.1.1) does not allow sending an entity-body in requests. Section 5.1.1 redirects us to section 9.x for the various … Read more
You can dynamically construct your authorization header using Beanshell PreProcessor as follows: Add empty HTTP Header Manager as a child of your request which requires authorization Add Beanshell PreProcessor as a child of the same request with the following code: import org.apache.jmeter.protocol.http.control.Header; sampler.getHeaderManager().add(new Header(“Authorization”,”Bearer ” + vars.get(“BEARER”))); This will construct fully dynamic header using BEARER … Read more

Yes HTTP RFC2616 available here says: Multiple message-header fields with the same field-name MAY be present in a message if and only if the entire field-value for that header field is defined as a comma-separated list [i.e., #(values)]. It MUST be possible to combine the multiple header fields into one “field-name: field-value” pair, without changing … Read more
By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF. In order to reduce the chance of CSRF vulnerabilities in CORS, CORS … Read more
The best HTTP header for your client to send an access token (JWT or any other token) is the Authorization header with the Bearer authentication scheme. This scheme is described by the RFC6750.
