Java Code Examples for org.apache.http.HttpStatus#SC_METHOD_NOT_ALLOWED

/**
 * Check whether remote directory exists.
 * If HEAD used by {@link #exists(String)} fails, GET is used instead.
 * 
 * See <a href="http://code.google.com/p/sardine/issues/detail?id=48">http://code.google.com/p/sardine/issues/detail?id=48</a>
 * and <a href="https://issues.alfresco.com/jira/browse/ALF-7883">https://issues.alfresco.com/jira/browse/ALF-7883</a> 
 * for more information and motivation.
 * 
 * This method should work both for WebDAV and plain HTTP,
 * hence PROPFIND can't be used.
 * 
 * @param url
 *            Path to the directory.
 * @return True if the directory exists.
 * @throws IOException
