URL Rewriting and Velocity

Hi
My question is does Velocity support URL Rewriting or I have to employ URL
rewriting with my own 
Implementation. I know that with Servlets you can do URL Rewriting while
printing out to the client. Since velocity
Does the printing out ,how can URL Rewriting be done using velocity.

What I do for Url rewriting directly in my templates is to add a handful of helper macros to the VM_global_library.vm (see below) and then ensure I always put the Servlet HttpResponse in the Velocity context under the name "response".

So when I need to rewrite an Url I just have to use the functions #Url, #QuotedUrl, #Redirect and #QuotedRedirect - see the doc...

The VM_global_library.vm snippet:

##
##	macro:			Url
##
##	parameters:		$url
##
##	description:	Encodes a link with servlet session information
##
##	prerequisite:	Servlet response required to be placed in the
##					context as 'response'.
##
##	html use:		<a href="#Url($link)">My link</a>
##

##
#macro( Url $url )
$response.encodeURL($url)#end

##
##	macro:			QuotedUrl
##
##	parameters:		$url
##
##	description:	Encodes a link with servlet session information and
##					adds surrounding quotes.
##
##	prerequisite:	Servlet response required to be placed in the
##					context as 'response'.
##
##	html use:		<a href=#Url($link)>My link</a>
##
##	July 2002, martin@technomation.net
##
#macro( QuotedUrl $url )
"$response.encodeURL($url)"#end

##
##	macro:			Redirect
##
##	parameters:		$url
##
##	description:	Encodes a redirect with servlet session information.
##
##	prerequisite:	Servlet response required to be placed in the
##					context as 'response'.
##
##	html use:		<a href=#Url($link)>My link</a>
##
##	July 2002, martin@technomation.net
##
#macro( Redirect $url )
$response.encodeRedirectURL($url)#end

##
##	macro:			QuotedRedirect
##
##	parameters:		$url
##
##	description:	Encodes a redirect with servlet session information and
##					adds surrounding quotes.
##
##	prerequisite:	Servlet response required to be placed in the
##					context as 'response'.
##
##	html use:		<a href=#Url($link)>My link</a>
##

##
#macro( QuotedRedirect $url )
"$response.encodeRedirectURL($url)"#end

Velocity itself doesn't know anything about URL rewriting, as it isn't 
specifically for the web environment.  You can add tools or data to 
your context to help with this, though - people do it all the time.

Another thing you might consider is looking at the web application 
frameworks that work with velocity.  See

    http://jakarta.apache.org/velocity/powered.html

for a list
