All known Subclasses: org.apache.commons.httpclient.NoncompliantHeadMethod,
| HeadMethod | | public class HeadMethod extends HttpMethodBase (Code) | | Implements the HTTP HEAD method.
The HTTP HEAD method is defined in section 9.4 of
RFC2616:
The HEAD method is identical to GET except that the server MUST NOT
return a message-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 entity implied by the
request without transferring the entity-body itself. This method is
often used for testing hypertext links for validity, accessibility,
and recent modification.

| Method Summary | |
| public int | getBodyCheckTimeout()
Returns non-compliant response body check timeout.
The period of time in milliseconds to wait for a response body from a non-compliant server. | | public String | getName()
Returns "HEAD". | | protected void | readResponseBody(HttpState state, HttpConnection conn)
Overrides
HttpMethodBase method to not read a response
body, despite the presence of a Content-Length or
Transfer-Encoding header.
Parameters:
state - the HttpState state information associated with this method
Parameters:
conn - the HttpConnection connection used to executethis HTTP method
throws:
IOException - if an I/O (transport) error occurs. | | public void | recycle()
Recycles the HTTP method so that it can be used again.
Note that all of the instance variables will be reset
once this method has been called. | | public void | setBodyCheckTimeout(int timeout)
Sets non-compliant response body check timeout.
Parameters:
timeout - The period of time in milliseconds to wait for a response body from a non-compliant server. |
| HeadMethod | | public HeadMethod()(Code) | | No-arg constructor.

| HeadMethod | | public HeadMethod(String uri)(Code) | | Constructor specifying a URI.
Parameters:
uri - either an absolute or relative URI
since:

| getName | | public String getName()(Code) | | Returns "HEAD".
"HEAD"
since:
2.0 |
| recycle | | public void recycle()(Code) | | Recycles the HTTP method so that it can be used again.
Note that all of the instance variables will be reset
once this method has been called. This method will also
release the connection being used by this HTTP method.
