Török Gábor gave me an idea.

// ...
var campaignMedium = <%= ViewData.Model.CampaignMedium %>;
var campaignSource = <%= ViewData.Model.CampaignSource %>;
var campaignName = <%= ViewData.Model.CampaignName %>;

// save the old hash
var oldHash = document.location.hash;

// add campaign data to the hash
document.location.hash = 'utm_source=' + escape(campaignSource) + ...;
pageTracker._setAllowAnchor(true);
pageTracker._trackPageview();
// restore the old hash:
document.location.hash = oldHash;

This way, you could create the campaign data in the backend, and then, pass it to the hash dynamically, and then restore it without user even noticing it. I.e. the campaign tracking is 100% independent of the real URL.
