Redirect multiple application URL's deployed under Apache Tomcat

Requirement :
I want the perform below redirection 
http://apex.xxx.kw:8086/hr  ==to==>  http://apex.xxx.kw:8086/hr/f?p=101
http://apex.xxx.kw:8086/fin ==to==>  http://apex.xxx.kw:8086/fin/f?p=107
http://apex.xxx.kw:8086/tech ==to==>  http://apex.xxx.kw:8086/tech/f?p=217

Solution:

STEP 1 : Add below entry in server.xml
Just below the line 
<Host name="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true">
add new line
		<Valve className="org.apache.catalina.valves.rewrite.RewriteValve" />

STEP 2 : Define redirection rules
Under Tomcat\conf\Catalina\localhost create a file [ rewrite.config ] with below redirection entries.
# Redirect /hr to /hr/f?p=101
RewriteRule ^/hr/?$ /hr/f?p=102 [R=302,L]

# Redirect /fin to /fin/f?p=107
RewriteRule ^/fin/?$ /fin/f?p=107 [R=302,L]

# Redirect /tech to /tech/f?p=107
RewriteRule ^/tech/?$ /tech/f?p=107 [R=302,L]


STEP 3 : Restart Apache Tomcat Services
Below redirection is performed post restart of Apache Tomcat Services,
http://apex.xxx.kw:8086/hr 		==to==>  http://apex.xxx.kw:8086/hr/f?p=101
http://apex.xxx.kw:8086/fin 	    ==to==> http://apex.xxx.kw:8086/fin/f?p=107
http://apex.xxx.kw:8086/tech	     ==to==> http://apex.xxx.kw:8086/tech/f?p=217

Note*****
If you have single URL, you can simply update the index.php file under webapps\ROOT directory and define the redirection rule there.
