Zend_Http_Client ” 77
// All cookies for the domain localhost.example with a path or
// subpath of /some/path
$cookies = $cookiejar->getMatchingCookies(
’http://localhost.example/some/path’
);
// All non-session cookies for the domain localhost.example
$cookies = $cookiejar->getMatchingCookies(
’http://localhost.example/’,
false
);
?>
Alternatively, getAllCookies can be used to access all cookies contained in the cookie
jar instance. When a cookie jar is only used to store cookies for a single domain,
getAllCookies offers a more concise method than getMatchingCookies to retrieve all
cookies for that domain. Like getMatchingCookies, getAllCookies also returns an array
of Zend_Http_Cookie objects by default.
R edir ection
The maxdirects configuration setting is an integer indicating the maximum number
of redirections to perform before terminating. U pon termination, the client
will simply return the last response it received. The isRedirect method of
Zend_Http_Response returns true for responses with a 300-level status code.
Sections 10.3.2 and 10.3.3 of RFC 2616 indicate that when a redirection occurs,
both the request method and parameters should be retained. In practice, most
clients don’t behave this way. Instead, parameters are cleared and the method reverts
to GET. F or consistency with other clients, Zend_Http_Client behaves this way
by default. To force it to be compliant with the RFC, the strictredirects configuration
setting can be set to true.
U ser Agents
The useragent configuration setting contains the user agent string to use and defaults
to ’Zend_Http_Client’.
