Get, post знаю. А еще есть какой-то head....
Просто к нам на сервер поступают какие-то запросы именно через head. И такое ощущение, как будто-бы наш сервак пытаются использовать как анонимный прокси.....
The HEAD method is identical to GET except that the server must not
return any Entity-Body in the response. The metainformation contained
in the HTTP headers in response to a HEAD request should be identical
to the information sent in response to a GET request. This method can
be used for obtaining metainformation about the resource identified
by the Request-URI without transferring the Entity-Body itself. This
method is often used for testing hypertext links for validity,
accessibility, and recent modification.
There is no "conditional HEAD" request analogous to the conditional
GET. If an If-Modified-Since header field is included with a HEAD
request, it should be ignored.
