clear or delete parameters from url?

[gabo]

hello, my servlet shows a table with customers. each customer has a link that calls the customer servlet with the parameter customerid, like this

<a href=\"/customer?customerid=7\">

so when the user clicks on the customer the url in the browser becomes

http://localhost:8080/customer?customerid=7

after the user edits and saves the customer the url remains the same, is there a way to make the url "http://localhost:8080/customer" after the user saves the customer data?
thank you
