| 37 | * Extract components of an "iiop" or "iiopname" URL. |
| 38 | * |
| 39 | * The format of an iiopname URL is defined in INS 98-10-11 as follows: |
| 40 | * |
| 41 | * iiopname url = "iiopname://" [addr_list]["/" string_name] |
| 42 | * addr_list = [address ","]* address |
| 43 | * address = [version host [":" port]] |

| 45 | * version = major "." minor "@" | empty_string |
| 46 | * port = number |
| 47 | * major = number |
| 48 | * minor = number |
| 49 | * string_name = stringified name | empty_string |
| 50 | * |
| 51 | * The default port is 9999. The default version is "1.0" |
| 52 | * US-ASCII alphanumeric characters are not escaped. Any characters outside |
| 53 | * of this range are escaped except for the following: |
| 54 | * ; / : ? : @ & = + $ , - _ . ! ~ * ' ( ) |
| 55 | * Escaped characters is escaped by using a % followed by its 2 hexadecimal |
| 56 | * numbers representing the octet. |
| 57 | * |
| 58 | * For backward compatibility, the "iiop" URL as defined in INS 97-6-6 |
| 59 | * is also supported: |
| 60 | * |
| 61 | * iiop url = "iiop://" [host [":" port]] ["/" string_name] |
| 62 | * The default port is 900. |
