Avoiding 403 errors with some apache configurations

URL to call piwik.php gives error 403 Forbiden with some apache configurations. Visitor is not registered by piwik.
When returning the URL to call piwik.php could it be possible to use relative url instead of absolute ones?
Some apache configurations don’t accept absolute url for security reasons.

ie:

emailMyName- Low-cost email address - 1GB email storage - Block spam - Web & POP3 email access - Get your name as your email addressmy-relative-url%2F&urlref=&_id=xxxxxx&_idts=xxxxx&_idvc=3&_idn=0&_ref=&_refts=0&_viewts=xxxxxxx&pdf=1&qt=1&realp=1&wma=1&dir=1&fla=1&java=1&gears=0&ag=1&res=1680x1050&cookie=1

works well.

How to get that modification?
