How to hide portal information

Hi Experts,

I had implemented external facing portal.

We are facing some issues:

1. How to hide the portal version in HTML view source code. Example If we right click on the web page view the source it will display portal version details. Like

Version:7.00001620,

Level:1,

PortalVersion:"7.00.200908152330";,

2. Same way it will show J2EE engine details also will display.

Like above it will display so many server related details. How to hide those server related details?

Please help me anyone how to resolve this issue.

Regards,

Satya.
