HttpHead

Class Overview

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.

[Expand] Inherited Methods
From class org.apache.http.client.methods.HttpRequestBase void abort() Aborts this http request. Object clone() Creates and returns a copy of this Object. abstract String getMethod() Returns the HTTP method this request uses, such as GET, PUT, POST, or other. ProtocolVersion getProtocolVersion() Returns the protocol version this message is compatible with. RequestLine getRequestLine() Returns the request line of this request. URI getURI() Returns the URI this request uses, such as http://example.org/path/to/file. boolean isAborted() Tests if the request execution has been aborted. void setConnectionRequest(ClientConnectionRequest connRequest) Sets the ClientConnectionRequest callback that can be used to abort a long-lived request for a connection. void setReleaseTrigger(ConnectionReleaseTrigger releaseTrigger) Sets the ConnectionReleaseTrigger callback that can be used to abort an active connection. void setURI(URI uri)
From class org.apache.http.message.AbstractHttpMessage void addHeader(Header header) Adds a header to this message. void addHeader(String name, String value) Adds a header to this message. boolean containsHeader(String name) Checks if a certain header is present in this message. Header[] getAllHeaders() Returns all the headers of this message. Header getFirstHeader(String name) Returns the first header with a specified name of this message. Header[] getHeaders(String name) Returns all the headers with a specified name of this message. Header getLastHeader(String name) Returns the last header with a specified name of this message. HttpParams getParams() Returns the parameters effective for this message as set by setParams(HttpParams). HeaderIterator headerIterator(String name) Returns an iterator of the headers with a given name. HeaderIterator headerIterator() Returns an iterator of all the headers. void removeHeader(Header header) Removes a header from this message. void removeHeaders(String name) Removes all headers with a certain name from this message. void setHeader(Header header) Overwrites the first header with the same name. void setHeader(String name, String value) Overwrites the first header with the same name. void setHeaders(Header[] headers) Overwrites all the headers in the message. void setParams(HttpParams params) Provides parameters to be used for the processing of this message.
From class java.lang.Object Object clone() Creates and returns a copy of this Object. boolean equals(Object o) Compares this instance with the specified object and indicates if they are equal. void finalize() Called before the object's memory is reclaimed by the VM. final Class<? extends Object> getClass() Returns the unique instance of Class that represents this object's class. int hashCode() Returns an integer hash code for this object. final void notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. final void notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. String toString() Returns a string containing a concise, human-readable description of this object. final void wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object. final void wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires. final void wait(long millis) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
