jsp form post without html???

[karen]

yes, i have looked through this group for the answer to ths before
posting, but i haven't found it. (although i've seen many similar
posts.)
so here's the question:

1. user clicks button on jsp page
2. button is really just a link to another jsp "page" (this page
performs db manipulation, but sends no html output, so it's
"invisible")
3. invisible page does the equivalent of submitting a form via post to
a url on another server

how to accomplish 3?? i cannot use response.sendRedirect() because i
do NOT want the form variables visible in the query string. if i
write to a URLConnection, the form variables are posted, but i don't
know how to make the browser actually move on to the URL that i write
to.

what is the answer??

thanks,
