Using URL alias on Livesite

System

Hi,

We are using the following products:
TS 7.1 (Windows 2008)
LS 7.1 (Linux)
Websphere portal (Linux)
IBM HTTP webserver (Linux)

We have installed LSDS on websphere portal server and portal server is rendering the Livesite pages.

We create pages using sitepublisher and publish it using the PLC workflow. We tried using the URL alias to create friendly URLs for each node and trying to access it through portal, and we are facing issues accessing it.(404 error)

The concept of URL alias works perfectly on a Tomcat server and we wanted to implement this on portal.

Tomcat page URL:
http://hostname:1776/sites/en_US/Test.page
Tomcat friendly URL:
http://hostname:1776/friendlyURL
Portal page URL:
http://hostname/wps/PA_crp/en_US/Test.page
Portal friendly URL:
http://hostname/wps/PA_crp/friendlyURL

Here, PA_crp (in the above portal URL) is the ear file that is deployed on the portal server.

Has anyone used the concept of URL alias on portal server? If yes, can you provide me the configuration steps.

I am also looking for any manuals that talk about the implementation of URL alias in Livesite so i can get some insights into it.

Thanks,
Arun.
