[jQuery] change browser url?

[jQuery] change browser url?


Hi,
i'd like to know if i can change the page url somehow.
for example:
let say the page's url is: http://groups.google.com/group/jquery-en/post
i would like to change it to: http://groups.google.com/group/jquery-en/bla
without reloading the page.
is that possible? if so how can i do that?
thanks for any help.
