How to hide parameters and path in urls

Hello Friends,

Please let me how can I hide the parameters passed in the website url. Like as below
suppose I have http://www.domainname.com/mysite/filename1.jsp?woodtype=teak%20trees&plant=balasha&model=balasha+2.4+wood&balashabrand=reeks&city=Bangalore&pincity=Bangalore&strarea=balasha&strstate=Karnataka&strpincode=&strcapacitycapty=&pricess=asc&chatmobilenumber=9999999999&sellername=kartheek

It should just show http://www.domainname.com nothing else. and also when we enter http://www.domainname.com/filename/web.xml the code is displaying but we even need to hide this from code displaying. Please do the needful.

Please do the help ASAP.

Thanks
Kiran.
