При попытки получить от яндекса результат запроса (xml.yandex.ru) методом POST, сервер выдаёт ошибку (причём похоже это наш сервр)
ERROR

Cache Access Denied
------------------------------------
While trying to retrieve the URL: {http://xmlsearch.yandex.ru/xmlsearch/}

The following error was encountered:
* Cache Access Denied.
Sorry, you are not currently allowed to request: http://xmlsearch.yandex.ru/xmlsearch/
from this cache until you have authenticated yourself.

You need to use Netscape version 2.0 or greater, or Microsoft Internet Explorer 3.0, or an HTTP/1.1 compliant browser for this to work. Please contact the {cache administrator} if you have difficulties authenticating yourself or {change} your default password.
