set_cookie_response {cookies}

Set cookie via HTTP header

Description

Send a shiny::httpResponse() that sets a cookie in the user's browser. Note that this does not return a full shiny ui.

Usage

set_cookie_response(
  cookie_name,
  cookie_value,
  expiration = 90,
  secure_only = NULL,
  domain = NULL,
  path = NULL,
  same_site = NULL,
  http_only = FALSE,
  redirect = NULL,
  ...
)

Arguments

cookie_name

The name of the cookie. Can contain any US-ASCII characters except for: the control character, space, a tab, or separator characters like ( ) < > @ , ; : \ " / [ ] ? = { }.

cookie_value

The contents of the cookie as a single character value.

expiration

Days after which the cookie should expire. To remove an HttpOnly cookie, send a negative value for this attribute.

secure_only

Logical indicating whether the cookie should only be accessible via secure (⁠https:⁠) requests (except on localhost).

domain

The host to which the cookie will be sent (including subdomains). If this is NULL (default) the cookie will only be sent to the host of the page where this cookie was set (not including subdomains).

path

The path that must exist in the requested URL for the browser to send this cookie. Includes subdirectories.

same_site

One of "strict", "lax" (default), or "none", indicating when the cookie should be sent. When same_site = "none", secure_only must be TRUE.

http_only

Logical indicating whether the cookie should only be sent as part of an HTTP request. When this is FALSE (default), the cookie is accessible to JavaScript via the Document.cookie property.

redirect

A relative or absolute URL where the user should be sent next. A typical case would be the same URL minus the query parameter that triggered the Set-cookie response.

...

Additional parameters passed on to shiny::httpResponse().

Value

A shiny::httpResponse() that sets the cookie.
