preserving existing url parameters when clicking page to page

Hi-

Lets say I'm on a node view page, and the url looks something like this:

http://mysite.com/node/10?foo=123&bar=456

When I click on edit, the url will turn into this by default:

http://mysite.com/node/10/edit

Is there an easy way to be sure that I am able to keep certain or all parameters in the URL:

1) in the specific case, from a node view to a node edit page
2) in the general case, when I click from any page to any other page, node view/edit, or otherwise

?

thanks,
geremy
