/**

* ServiceLink used to discard all cached data (templates, specifications, et cetera). This is
|
|
30 |
* primarily used during development. It could be a weakness of a Tapestry application, making it
|
|
31 |
* susceptible to denial of service attacks, which is why it is disabled by default. The link
|
|
32 |
* generated by the ResetService redisplays the current page after discarding all data.
