Usage

From source file:eionet.cr.util.URLUtil.java

/**
 * Connect to the URL and check if it exists at the remote end. Local identifiers are removed (the part after the '#') before
 * connecting. The method returns true (i.e. URL is considered as "not existing") if the given URL is malformed, or its
 * connection throws a {@link UnknownHostException} or sends a HTTP code that is 501 or 505 or anything in the range of 400
 * to 499. The latter range, however, is ignored if the given boolean input is is true (meaning a client error is OK).
 *
 * @param urlStr the URL to check.//from  www. java2s .c  o m
 * @param clientErrorOk If true, then a response code in the range of 400 to 499 is considered OK.
 * @return As described above.
