How to pass argument to Page

I wanted to pass argument to page using URL. I tryed below option:

http://localhost:4502/cf#/content/mysite/en/add-product-page.html?pid= 123

I am able to pass argument in URL and also able to access. But the problem is for this kind of pages it refreshes page after loading. If I do not pass the argument it loads normaly, where as with argument it flickers visibly. What can I do to avoid this?

Purpose: I have product page and I wanted to display product information on page based on ID passed to the page.
