According to RFC2396[1], it is: |
| 7 |
|
| 8 |
2.3. Unreserved Characters |
| 9 |
|
| 10 |
Data characters that are allowed in a URI but do not have a reserved |
| 11 |
purpose are called unreserved. These include upper and lower case |
| 12 |
letters, decimal digits, and a limited set of punctuation marks and |
| 13 |
symbols. |
| 14 |
|
| 15 |
unreserved = alphanum | mark |
| 16 |
|
| 17 |
mark = "-" | "_" | "." | "!" | "~" | "*" | "'" | "(" | ")" |
| 18 |
|
| 19 |
Unreserved characters can be escaped without changing the semantics |
| 20 |
of the URI, but this should not be done unless the URI is being used |
| 21 |
in a context that does not allow the unescaped character to appear. |
| 22 |
|
| 23 |
So, foo/(123)/ is valid. ASP.NET makes use of this to include the |
| 24 |
session ID in the URL. Not really on topic here, but it's the only place |
| 25 |
where I've seen parentheses in URLs. |
