When publish your content, you don't want to have the full path in your links. So you map /content/geometrixx/en/products.html to /geometrixx/en/products.html, you can do this using the jcr resource resolver[0], this will map outgoing links. However, you will run into issues with Dispatcher. Your incoming request http://myserver/geometrixx/en/products.html get's mapped to: /docroot/httdocs/geometrixx/en/products.html
However when you activate the content, and try invalidate it in Dispatcher, dispatcher looks for the full content path: "/docroot/httdocs/content/geometrixx/en/products.html" So in order to cache/invalidate the requested URL to the correct path, you need to rewrite the incoming URL from the shortened version to the full path i.e. from "/geometrixx/en/products.html" to "/content/geometrixx/en/products.html" This is what is done with mod_rewrite
You can also use mod_rewrite to rewrite incoming requests for root "/" to /content/mysite/index.html"

You can find all the details you require from the Apache HTTP Server documentation:
http://httpd.apache.org/docs/2.2/configuring.html
http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html
Do you have a specific query?

Hi,
Thank you for your reply.
I am not getting as to why URL Re-write module is installed and configured [lets say on IIS]. What exactly is the purpose of it.

I recommend you read this excellent tutorial on caching: https://www.mnot.net/cache_docs/
Mod_expires manipulates the Expires headers returned from the hosting server, letting you control how long a client's Web browser caches resources. You want to tune the duration of your caching to optimize performance while still considering how often you update the resource.
Also explained here in relation to static content which does not change:
