Infinite Loop Page Reload?

I have a problem of an infinite loop.The problem is found at:

http://truth-and-opinion.dyndns.org/BoR/

This page was created with minimal script, taken out of a larger more complex page.The body element is set with the onload attribute which calls a handler to initialize the content. In particular, I want to initialize the URL with a query substring: "?p=X" where X is a number from 1 to 10, corresponding to pseudo-page content. This is done by setting the page URL with the location.search property.But the problem with this appears to be that setting the location.search property causes another onload event, which then calls the initializing handler and sets location.search property again.

Setting a global such as locSearchInProgress to a boolean and testing if it is true within the initializng handler to cause it to return and thus to prevent execution of the location.search assignment statement is not helping.I have tried using .stopPropagation() and .preventDefault() methods while developing in FF, but have been unsuccessful.Is there a way to update the URL using a location.search assignment without triggering onload?

What is a "pseudo-page"? There is actually only one HTML document (index.html), and it has ten DIV elements that are NOT displayed (CSS property "display:none"). After the user initiates a click event on the part of the document that is an interface for content / pseudo-page selection, any one of the DIV elements can be called using document.getElementById(), and its content put into a DIV that displays the content using a contentNode.replaceChild().Thus page navigation is script-based using hidden content fetched into a visible container.
