How can I clear url parameters

[andr4578]

I'am working with Zend Framework and I have the following problem:

just for e.g.
I have few controllers and few actions in each controller
In view I've created few links in such way:
<a href="<?php echo $this->url(array('controller'=>'controller1', 'action'=>'action1'))?>">simple link to controller1 action1</a>

<a href="<?php echo $this->url(array('controller'=>'controller1', 'action'=>'action2', 'id'=>'123'))?>">link to controller1 action2 with parameter</a>

So the problem is when I follow the second link "link to controller1 action2 with parameter" I get following url http://mywebsite .com/controller1/action2/id/123 but when follow the first link "simple link to controller1 action1" parametr in the url stays and I get following url http://mywebsite .com/controller1/action1/id/123
