changing request url

[popprem]

Hi,

I have a requirement in which i need to change the request
url and send it. For example i need to change all
"/xxx/yyy/zzzz/..." urls as "/xxx/zzzz/..." ("/yyy"
removed from request url)and send it.
How can i do it without response.redire ct in servlet ???

Is there any way to achieve this through struts 1?

Thanks in advance.
