GET in HTML and Not PHP

I want to process a GET extension in a HTML page and not a PHP page.

I have looked through the internet and not found anything.

URL = examplesite.com?id=1234

I assume this would go to the index page on the domain. As the index page is a HTML page, is there a way to get the details of the extension transferred to another link I have in the html script that emails me when someone looks at the site.

This way I can customise the extension to know where the person found me. id=1234 is from twitter, id=2345 from FB etc.

Then i could place the extension onto the script to send me the email.

Is there a way to get the HTML page to process extension and pass it on in a variable of some sort.

Thanks in advance
