Hi

1) .htaccess
2) <Directory> tag

Whichis best to use?
And i read abput both, but being new i am not able to get the thing. I read that .httpd.conf file should bt there in my machine to reqrite. But i serach the whole PC but didnt get that file. DO i have to install mod_rewrite. I have tomcate 6.0
I wnat to achieve following thing :

IF user enters the ....
http://localhost:8080/mySite/pgHome

http://localhost:8080/mySite/section=pgHome


What thing i have to write where? Which filter string i have to wrtie? Its urgent. Can anybody tell me? I am working in NetBeans. And after creating file where to keep it? and do i have to explicity install mod_rewite?

Thanks in advance.

Hi

I have installed : apache-tomcat-6.0.14.exe
It donet have httpd.conf
which version i have to install to use URL rewriting?

Please remember that Apache web server and Apache Tomcat are two separate applications. The configuration file httpd.conf is part of the web server. Also, URL rewriting must be handled by the web server. This is not for Tomcat.

OMG, i was totaly in wrong direction till now ! Thanks a lot dear. I was really confused about apache and apache tomcat.

cant we achieve URL rewriting with tomcat ? to i have to add plug-inns in tomcat to achieve it? what to do for that?
