Extract components of an "iiop" or "iiopname" URL. The format of an iiopname URL is defined in INS 98-10-11 as follows: iiopname url = "iiopname://" [addr_list]["/" string_name] addr_list = [address ","]* address address = [version host [":" port]] host = DNS style host name | IP address version = major "." minor "@" | empty_string port = number major = number minor = number string_name = stringified name | empty_string The default port is 9999. The default version is "1.0" US-ASCII alphanumeric characters are not escaped. Any characters outside of this range are escaped except for the following: ; / : ? : @ & = + $ , - _ . ! ~ * ' ( ) Escaped characters is escaped by using a % followed by its 2 hexadecimal numbers representing the octet. For backward compatibility, the "iiop" URL as defined in INS 97-6-6 is also supported: iiop url = "iiop://" [host [":" port]] ["/" string_name] The default port is 900.
