Cookie keeping in Apache proxy

Hi All,

First the question:
Does Apache, when set as a proxy, can be configued to keep the
session/cookie details of the sites visited?

The problem:
I would like to build an application that centralize a searching
operation
for verious search engines. some of which may require a login.
When returning the search results to the end-user, the session/cookie
details from the relevant search engine are missing. When the end-user
will
click on one of the links he will be prompted to enter the user and
password
all over again.
I am looking for a way to keep the session/cookie in a central place
(proxy) and I
was considering using Apache as a proxy.

Is that the right way?

Best regards,
Hanan
