Are you trying to something to the effect of this?
if url has "abc"
Display the alphabet on the right side
if url has 123
Display the numbers 1-9 on the right side
If so, you can use the $core_v2_page.GetQueryStringValue(parameter_name) method in a widget to retrieve the query string value with that name. Then, based on that value, select what content to render. You would just place your widget on the right side of the layout.
With this you could send the user to telligent.com and in your widget do $core_v2_page.GetQueryStringValue("display") which would return "abc".
