Apache reverse proxy and cookie

[momilla]

hi all!

I have a problem with the apache configuration as a reverse proxy.
I succeed in configuring the reverse proxy modules but apache don't sign in the correct way my cookie and, when my jsp application try to open a new page, the url is wrong.
I've read that it was a problem of some old version, I use the 2.0.54 and I also try to install the 2.1.6-alpha but the result is the same.
may anyone help me and tell me where I'm wrong?

thanks!
