Hi Ashok, welcome to the TOD forums!
What DNN version are you running? You placed the Inventua.HrefExchanger.dll into your bin directory and modified you web.config file as outlined in HrefExchanger.Help.htm and you disabled DNN 3.0 friendly URLs under "host settings"?
As long as the above went well, you should not have to do anything else. The friendly URL will be formed from your page (tab) name. So if you have a page called "Contact Us" your URL will look like
http://www.cactusglobal.com/contact+us.aspx.
Quoted from HrefExchanger.Help.htm: "If your tab name contains spaces, they will be replaced with plus signs. If your tab name contains an ampersand (&), plus sign(+), dot(.), forward or backslash (/, \) or question mark (?), the URL will not be rewritten, as these two characters are reserved characters for URLs. Using the tab name as the friendly URL gives you complete control over what your friendly URL will be."
For a "real world" example visit

Also, you will not see any friendly URLs while logged in as admin or host. Let us know if you have more questions.
Tom
