in zend framework, is there anyway i can check if a route exists from code?
example
say the following routes/urls are valid (point to controller/action)
/users
/users/1 // /users?id=1
/users/page/1 /users?page=1
/users/tagged/tagname/page/1 /users?tagged=1&page=1
if the user tries to goto /users/nonexistantpage
it should fail. soemthing to check if the user request the url, will it fail, but on the code level.
