CSS 11500 url path rewrite and NAT

Question

Hi,
We are evaluating a CSS 11500 and try to configure url path rewrite and NAT, but we have some problems.
What we would like to do is the following:
http://www.example.com/path1 -> http://host1:80
http://www.example.com/path2 -> http://host1:8080
http://www.example.com/path3 -> http://host2:80
The address www.example.com is resolving to a valid internet address, whereas host1 and host2 resolves to private IP addresses.
The client should always see the external url (e.g. http://www.example.com/path1/...) and the CSS should do the necessary translation.
Any help would be very much appreciated!
Regards,
Harald

Hello Experts, I'm new with this cisco stuff too(just got it 3 weeks ago), but here is some of my experience with cisco css 11501.
First : Service ServerName, there is a port setting here, but from my experience, I think it is related with KeepAlive option, so, port is alternate way to know if the server alive or not.
Second : When you send request to cisco css, the port option in content port will be the cisco css port to accept request, so, if you send a request to http://vip:8080/, all service must be in the same port too to balance the request, in this case, port 8080, if one service port 80, i'm sure the css will not hit the server.
Third : To solve your problem...
http://www.example.com/path1 -> http://host1:80 (ipA)
http://www.example.com/path2 -> http://host1:80 (ipB)
http://www.example.com/path3 -> http://host2:80
if you are lazy to buy new nic, just set subinterface/ip alias on the host1, and make the webserver only bind to specific address, not to all interface...
O yea, about your path1/path2/path3 -> /, hmm, i'm still asking in this forum about path changing cause until now, i haven't know how to do this, i know about apache rewrite module, and success do this, if only i know about this in cisco css too :-(
I'm sorry if I make mistake, I'm just telling my experience...
