HTTP Redirections

By default, Zend_Http_Client automatically handles HTTP redirections, and will follow up to 5 redirections. This can be changed by setting the 'maxredirects' configuration parameter.

According to the HTTP/1.1 RFC, HTTP 301 and 302 responses should be treated by the client by resending the same request to the specified location - using the same request method. However, most clients to not implement this and always use a GET request when redirecting. By default, Zend_Http_Client does the same - when redirecting on a 301 or 302 response, all GET and POST parameters are reset, and a GET request is sent to the new location. This behavior can be changed by setting the 'strictredirects' configuration parameter to boolean TRUE:

Example 478. Forcing RFC 2616 Strict Redirections on 301 and 302 Responses

// Strict Redirections
$client->setConfig(array('strictredirects' => true));

// Non-strict Redirections
$client->setConfig(array('strictredirects' => false));

You can always get the number of redirections done after sending a request using the getRedirectionsCount() method.
