I developed my own extension on the fix.
In short the get parameters are used in the cache ID. So in order to bypass this, I created an extension that changed the following:
/app/code/core/Enterprise/PageCache/Model/Processor/Category.php
Two functions where changed
protected function _getQueryParams()
AND
public function getPageIdWithoutApp(Enterprise_PageCache_Model_Processor $processor)
/app/code/core/Enterprise/PageCache/Model/Processor/Default.php
One function was changed
public function getPageIdWithoutApp(Enterprise_PageCache_Model_Processor $processor)
Once changed, it no longer created the cache ID with my specified tracking parameters.
example:
public function getPageIdWithoutApp(Enterprise_PageCache_Model_Processor $processor)
{
$queryParams = $_GET;
ksort($queryParams);
/**
* unset known tracking codes
*/
unset($queryParams["trk_msg"]);
unset($queryParams["trk_contact"]);
unset($queryParams["utm_source"]);
unset($queryParams["utm_medium"]);
unset($queryParams["utm_term"]);
unset($queryParams["utm_campaign"]);
unset($queryParams["utm_content"]);
/** End Edit */
$queryParamsHash = md5(serialize($queryParams));
return $processor->getRequestId() . '_' . $queryParamsHash;
}
