|

|
|
* 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.
