| /** |
| * |
| * This class implements a Text_Wiki_Parse to embed the contents of a URL |
| * inside the page at render-time. Typically used to get script output. |
| * This differs from the 'include' rule, which incorporates results at |
| * parse-time; 'embed' output does not get parsed by Text_Wiki, while |
| * 'include' ouput does. |
| * |
| * This rule is inherently not secure; it allows cross-site scripting to |
| * occur if the embedded output has <script> or other similar tags. Be |
| * careful. |
