To reset the counter, you have to clear your browser cache and delete cookies at the same time.
Just disabling JavaScript and/or Cookies will not help, just clearing the cache alone won't either.
Most Browsers offer an uncached refresh with CTRL+F5 if you want to try.
If Cookies are enabled (see above) you will find that the Counter will still persist and increase with every reload.
You have to disable or delete Cookies and clear the Cache before performing any Type of Request again to reset the Counter.

We can't detect if this works or not as of now. You have to try.
This method is used by Ad Agencies to track People and is resistant to clearing the Cookies. It abuses the ETag Header, which is normally used to handle caching of Resources. The Cookie is used as a Backup in case the ETag value is not sent by the client (cache deleted).
This works because a Server can simulate that the Value sent back from the Browser has expired. The Server then updates the Value and sends new Content.
The information below is from the Perspective of the AdThis Technology brings multiple Advantages over a traditional Cookie only approach
ETag is resistant against Removal or Blocking of Cookies.
ETag is a feature of the HTTP Protocol itself. Neither JavaScript nor Cookies are required for it to work
All Browsers implement the ETag Feature
The ETag Cookie is automatically handled by Server and Browser. Users will not notice it
ETags work with any Type of Resource as long as a Request is involved.
This means a static Request to /some-ad can still deliver different Content each time it's requested.
There are almost no Format Requirements for the Value of the ETag
No Browser offers Users a Way to edit ETags, which means the Value is faked out less likely
The Tag is bound to a user rather than an IP address
This Technology also comes with a few Disadvantages
If the User or the Browser cleans up the Cache, the Tag can get lost. Browsers clean old Items from the Cache to keep the Size small and the Content relevant. Depending on how much new Content is cached, this can happen sooner or later. This Issue can sometimes be mitigated by combining the Header with a Cookie and using the Cookie as a Backup in case the Header is missing.
The URL to deliver a certain Tag must always be the same. It doesn't has to deliver the same Content Type at all. Switching between Video and Images is possible if the Page that includes the Ad knows beforehand what Type is delivered.
The Value of the ETag has to be rather short, for example a User Id. The Length of this sites ETag is 46 bytes. In our case, it's an encrypted view counter.
There is currently no real Protection against this Type of Tracking. Users can sort of protect themselves by instructing their Browsers to delete all Browser Data on every Exit. This would cause Ads to see Users as new after every Browser Restart. A Downside for the User is that all Sessions and Site Settings are also lost. Browsers could be trained to ignore ETag if a Resource changes too often.
