cowboy_req:set_resp_header(3)

+ +

Name

+

cowboy_req:set_resp_header - Set a response header

+

Description

+
+
set_resp_header(Name, Value, Req :: cowboy_req:req())
+	-> Req
+
+Name  :: binary()  %% lowercase; case insensitive
+Value :: iodata()  %% case depends on header
+
+

Set a header to be sent with the response.

+

The header name must be given as a lowercase binary string. While header names are case insensitive, Cowboy requires them to be given as lowercase to function properly.

+

Cowboy does not allow duplicate header names. Headers set by this function may be overwritten by those set from the reply functions.

+

Use cowboy_req:set_resp_cookie(3) instead of this function to set cookies.

+

Arguments

+
Name
+

Header name as a lowercase binary string.

+
+
Value
+

Header value.

+
+
Req
+

The Req object.

+
+
+

Return value

+

A new Req object is returned.

+

The returned Req object must be used from that point onward, otherwise the header will not be sent in the response.

+
