I just want to show my root URL address whenever people browse into other pages of my site. How do I do this in dtml or python script or external method??
If I understand what you're asking, there's only one "good" way to do that: place your content in an iframe (or regular frame). You might modify main_template to do this. The frame's contents could change, but not the URL (since the "container" page is still the same.) You can see this effect in the ZMI.
Both techniques are easily defeatable by users.
But please note, this is very hostile web design. I would suggest you re-think your need for such a "feature".
