If the method is called with a string as argument, it returns either the given configuration if it is set, or null, if it's not set.

If the method is called with an array as argument, it will set the cookie configuration to the cookie container.

Options (when setting a configuration)

• value: Value of the cookie
• expire: Time the cookie expires in
• path: Path the cookie applies to
• domain: Domain the cookie is for.

cors()source public

cors( CakeRequest $request , string|array $allowedDomains , string|array $allowedMethods array() , string|array $allowedHeaders array() )

Setup access for origin and methods on cross origin requests

This method allow multiple ways to setup the domains, see the examples

Full URI

URI with wildcard

e.g cors($request, 'http://*.cakephp.org');

Ignoring the requested protocol

e.g cors($request, 'www.cakephp.org');

Any URI

e.g cors($request, '*');

Whitelist of URIs

e.g cors($request, array('https://www.cakephp.org', '*.google.com', 'https://myproject.github.io'));

Parameters

CakeRequest $request

string|array $allowedDomains

List of allowed domains, see method description for more details

string|array $allowedMethods optional array()

List of HTTP verbs allowed

string|array $allowedHeaders optional array()

List of HTTP headers allowed

disableCache()source public

disableCache( )

Sets the correct headers to instruct the client to not cache the response

download()source public

download( string $filename )

Sets the correct headers to instruct the browser to download the response as a file.

Parameters

string $filename

the name of the file as the browser will download the response

etag()source public

etag( string $tag null , boolean $weak false )

Sets the response Etag, Etags are a strong indicative that a response can be cached by a HTTP client. A bad way of generating Etags is creating a hash of the response output, instead generate a unique hash of the unique components that identifies a request, such as a modification time, a resource Id, and anything else you consider it makes it unique.

Second parameter is used to instruct clients that the content has changed, but sematicallly, it can be used as the same thing. Think for instance of a page with a hit counter, two different page views are equivalent, but they differ by a few bytes. This leaves off to the Client the decision of using or not the cached page.

If no parameters are passed, current Etag header is returned.

Parameters

string $tag optional null

Tag to set.

boolean $weak optional false

whether the response is semantically the same as other with the same hash or not

Returns

string

expires()source public

expires( string|DateTime $time null )

Parameters

string|DateTime $time optional null

Valid time string or DateTime object.

Returns

string

file()source public

file( string $path , array $options array() )

Setup for display or download the given file.

If $_SERVER['HTTP_RANGE'] is set a slice of the file will be returned instead of the entire file.

Options keys

• name: Alternate download name
• download: If true sets download header and forces file to be downloaded rather than displayed in browser

Parameters

string $path

Path to file. If the path is not an absolute path that resolves to a file, APP will be prepended to the path.

array $options optional array()

Options See above.

Multiple headers

e.g header(array('Location' => 'http://example.com', 'X-Extra' => 'My header'));

String header

e.g header('WWW-Authenticate: Negotiate');

Array of string headers

e.g header(array('WWW-Authenticate: Negotiate', 'Content-type: application/pdf'));

Multiple calls for setting the same header name will have the same effect as setting the header once with the last value sent for it e.g header('WWW-Authenticate: Negotiate'); header('WWW-Authenticate: Not-Negotiate'); will have the same effect as only doing header('WWW-Authenticate: Not-Negotiate');

Parameters

string|array $header optional null

An array of header strings or a single header string - an associative array of "header name" => "header value" is also accepted - an array of string headers is also accepted

httpCodes()source public

httpCodes( integer|array $code null )

Queries & sets valid HTTP response codes & messages.

Parameters

integer|array $code optional null

If $code is an integer, then the corresponding code/message is returned if it exists, null if it does not exist. If $code is an array, then the keys are used as codes and the values as messages to add to the default HTTP codes. The codes must be integers greater than 99 and less than 1000. Keep in mind that the HTTP specification outlines that status codes begin with a digit between 1 and 5, which defines the class of response the client is to expect. Example:

httpCodes(404); // returns array(404 => 'Not Found')

   httpCodes(array(
       381 => 'Unicorn Moved',
       555 => 'Unexpected Minotaur'
   )); // sets these new values, and returns true

   httpCodes(array(
       0 => 'Nothing Here',
       -1 => 'Reverse Infinity',
       12345 => 'Universal Password',
       'Hello' => 'World'
   )); // throws an exception due to invalid codes

   For more on HTTP status codes see: http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html#sec6.1

Returns

mixed

associative array of the HTTP codes as keys, and the message strings as values, or null of the given $code does not exist.
